The perfect video for my research. I have almost the same project in mind. I hope the radishes you grew were firm and crispy.
More please!! I really appreciate you for taking the time to cover these topics. I'm excited to see what more you can come up with.
im trying to purchase a house soon and ill be able to finally build a lot of hydroponic stuff and automate a lot of things with arduino and RPI so stayed tuned,
I am updating a attic exhaust fan that has been in this house for over 25 years and does not currently work, this is exactly what I needed. You have done a great step by step instructional tutorial Thank You!!!!
no problem thanks for watching
This is great. I am planning to build a cooling system for my heat frame box that I use for germinating seeds before planting. They need to be kept at a certain temperature and this will be just what I was thinking about.
You're doing a great job explaining this. I just made a clone box and this will work perfectly! Thank you
Glad it helped!
Thank you for this idea. I will be using this to control a misting system in my new NVAC Aquaponic Greenhouse. Looks like a fun project
Dang!!! I wanna build a greenhouse and automate the heck out of it. When you get this all setup please share a imgur link or somethign I really want to see it.
Thank you so much! Very simple, but not overly simplistic project and great for learning practical digital electronics.
Thanks for watching!
Nice video and good job at soldering descriptions. I am making a sketch for work to control temp for powdercoating ovens.
Perfect for my wine/root cellar exhaust fan. I changed it to read two temps and only exhaust if hotter inside than out, 👍
Thank you
I don't need to be in the giveaway, just wanted to say that you've made a nice and smooth video. Easy to listen to, and you've covered a lot of stuff. I've subscribed.
Thanks a lot Jack, I hope you continue to enjoy the stuff i produce!
Quite honestly on of the best explained video i have ever seen very neat sucinct and to the point !!! Brilliant well done
Wow, thanks!
Wow amazing video. Well made. Very well explained. I was thinking of making one so my fan can turn on when heater is on and fan off when the heater is off.
Thanks for this video, I'm looking forward to adding a fan like this to my Bee Hive, for hot summer days.
very cool usecase!
This really good tutorial, thank you. Also your hands may be shaky but the those two solder looked really good :)
Been looking for a way to keep my surveillance dvrs cool, this will work perfectly!
Good luck on your project!
cool! I will use the Arduino for home Temperature control!
Hi! I'm strugling to grow some of my plants. Building some automated control will maybe help to understand what my greens are going through and maybe fix it. Nice 'hack' btw, keep going :)
Very cool! excellent detailed explanation.
A nice tip for holding the pins in place to solder --- u could insert them into the Arduino holes then stab the other long ends into a piece of foam like packing foam. Or styrofoam.
I sometimes use a kneadable eraser for holding the pins too.
Just mentioning in case it helps you or anyone who reads.
I’m trying to make a smoker temp controller, this should work perfect
Nice! I have a project coming up that is similar to your video tutorial.
LoL, before I clicked on your profile I stumbled across your channel and thought you were some smart pot head growing weed! Good job explaining it, easy to follow.
lol, thanks for watching!
Awesome... thank you... can you also attach a humidity sensor to the same arduino?
Hello,
Thnx a lot for your great RUclips, It means a lot if you share what you’re good in, so we can learn from each other. I hope you have time for a small simple question. Is there power on your relay coil when the NO contact is closed (when you’re hooked up fan is on) like a standard relay or does it gets a pulse each time you switch on and off you’re fan?
Greats

Amazing project! Im thinking of using this for an ebike for cooling etc. But they would need a few volts. Is it possible?
Yes! i found what may work for my project. I'm building a heating system useing an radiator from a truck. Paint it black, put in a box with glass top mount it on the roof. The sun will heat the fluid (Radiator Fluid or Oil). After reaching around 200*, a valve would open & a 12v pump would push the hot fluid into a hot water holding tank. Then useing a radiator with a fan on the back side. Mounted inside the room you want to heat. the heated fluid pulled from the hot holding tank the, fan would blow the heat into the room. Then the cooled fluid go into a cold holding tank to go back to the roof to be heated again. A closed system with everything running on a 12v or 24v solar system. Controlling the system will be a learning cruve for me. Temp sensor, Open/Close valves, Fans & blowers.. This will help me get started. Thanks
wow very interesting application! good luck I love the idea
Nice project but a tip of advice.
Never, Ever solder mains cables no matter what, the reason for this is as simple as that the solder tension will adjust to the pressure of the connector and in the end will end up in a fire, there's a reason why this is illegal in some country when installing mains inte building.
interesting! thanks for the info
I would wire an arduino to my fan in my room and program it to turn on when the temperature reaches above 80 degrees fahrenheit!
Would be cool to make for a kitchen exhaust fan, or with my compact fluorescent set up, or for use in a terrarium. New to Arduino and coding so I will be checking out more of your videos.
Neat idea. So if I want to make it automatically turn on everytime I cook, what sensor should I use? Air quality sensor?
Depending on where you want the fan and where you put the sensor, and considering the space available and size of your cooking area. I would just stick with the temperature sensor in a good place and then adjust your temperature range for the ideal setting. Multiple sensors would be cool also; thinking a humidity sensor would be suitable. Not knowing much about the air quality sensor, I wouldn't know what parameters you would want to trigger the fan at.
tnk s . 👍 and subscribed . it wass what i m searching
awesome!
Thank you so much sir for the tutorial.. I want to make it for my school project. i.e temperature to control the speed of the fan. Please requirement for speed.
Hi. Another great video! This is a great project as always! Unfortunately I do live in the UK and would be prepared to pay shipping but I would love to enter the give away. I would make a small weather station to feed data back like wind temperature, wind speed and more.
I finally made a "tech" video! Im glad you liked it!
Soldering tip time....soldering iron goes on one side of the component and board, the other side of the component goes the solder that is touching the component and board. Solder should simultaneously melt on the component and board at the same time and you will have a nice shiny solder joint, this means it didn't get too got and you got good flow from the flux.
Thanks for this well explained video......
Glad it was helpful!
Very cool i will make sensor temperature for may room
Considering this is a final assembly, It would probably be easier to solder a wire under the header on the Arduino from Aref to 3.3v rather than try to put two wires in a crimp connector.
yeah that's a really good idea, funny how you can miss something so obvious! Ill have to redo it with that method. thanks for watching and thanks for the advice!
I have gone through this video and found to be useful to me; Thanks for this presentation which has taught me in detail about arduino with temperature sensor. I would like to have a presentation by you using the DHT11/22 sensors to sense the humidity and temperature and to drive external circuits of exhaust and sprinkler for my kitchen garden green house.Hope my request will receive your kind attention.
Wonderful!
I'd like to experiment with an Turbo Intercooler misting project if I can obtain parts for this.
Good design mate. Not bad at all. Probably agree with Zarouszz. I am very fussy with Ac (I'm a 220er). Don't worry about the prizes for me (foreigner anyway), but that is very cool of you. Don't see small peddlers doing that often... Puts a bit of faith back in humanity as far as im concerned to well done bud./ Ill keep watching as a result of your kindness
AC is scary I git it running DC fans now
Excellent. Continue.
I'm hoping to do more tech videos soon
Great video. It's old as hell but I try it anyway. I bought all the parts and put everything together. But my temperature reading in the monitor goes down when I apply heat. The base temperature is 27.27 F. And even if I uncomment the Celsius line and comment the Fahrenheit line, I will still get a reading of 27.27 F. What did I do wrong?
Nicely done.... why not just solder some leads streight to the temp probe.... and skip the dupont and headerpins.... or even just plug the legs of the probe streight in to the dupont connector? On the board side the dupont makes more sence... but that just me :)
Very interesting project👍
BTW we have a plan, by using the ECT sensor from a car (fluctuate voltage will be availabe from 0.9 to 3 volt), to trigger the 3/5 v relay module, so it switch on/off a mass signal to a 12v fan relay. Is it Possible??
I'm not sure I'm not an expert on the wide range of uses and configurations
This is awesome. Would you be interested in tutoring through a small similar project with an Arduino, thermistor, and heating element? I'd be willing to pay for a session or two.
Hi, I really like your video! I would like to create something similar for my 3d printing hobby but I want to use a DS18B20 sensor that has data, Vcc and ground pin. How should I hook it up? would it work with your arduino program?
Ill have to do some research
Please do a similar video with a bigger fan and a triac for speed control! Maybe raspberry pi, too!
ok
Nice!
Thanks!
can I use another type of temperature sensor?
i m trying to make an automatic ac ceiling fan.will it work
Very cool. Nice explanation, subscribed. Can you please provide a link where I can buy? I really want to try this.
there are links in the description to buy the three parts.
youll have to provide the fan you would like to use.
Also there are links in the description for the program and drivers, Thanks for the sub and watching the video. Dont buy anything yet. because im going to randomly pick 2 people from the comment section and mail them the parts! You might win! ( do you live in the usa? )
Techplant Silly me, just seen the description. How cool and yes I live in the US. Also just watched your succulent video, good stuff man. Enjoying the videos. Fingers crossed for the win.
I want to use it do an external cardiac massager for doing a CPR machine
did you build this yet, sounds scary!
I'm trying to do something similar, except that instead of a fan its a cooler for a diy minifridge. i cant get the arduino sketch to upload. would you be able to look at the errors and see whats wrong. ive never worked with arduinos so im not sure what im looking at
if you have an off brand one youll need their firmware
I would google your exact brand and get the specific help it needs
Hi,
I found your nice ventilator system, which is practically what I want to built; however, the use of the ventilator is slightly different:
I have in my central heating system in the house (a.o.) a vertically positioned radiator. The top of the radiator is about 50cm under the ceiling, consequently the heat builds up above the radiator. On top of that I have n old house with wooden beams supporting the ceiling which make the heat stay put between the beams.
I have bought 2pcs 'be quiet' ventilator s12V, and want to make the system more or less similar to what you made.
A temp sensor should respond at 40°C or so and blow the heat into the room.
The ventilators are with 3 wires and it would be nice to have them start slowly (at half speed) and keep them running at half speed if the high temp setting can be maintained at that moment; if the temp runs over the high temp setting it should switch to full speed.
I do realize this is quite something, but if it works, most likely more people can make use of it because I believe in the end it saves money when you can enjoy the (expensive) heat in the room instead of creating a warm ceiling.
regrards,
Tom
So here my question, is that fan can reduce the temperature from the sensor?
Sorry for my bad english. Pls answer, because i have a project seems like this i wanna know if the fan can refuce a temperature.
if the fan is sucking cold air from somewhere else it can.
Can you control 2, 4 or more (how many?) fans with only one arduino? Thanks
yes, you just need a larger relay, there are 2 4 8 and 16 channel ones on amzon
Hi, great project...question: is it possible to change your circuit to "Celsius" not "Fahrenheit" ?
Yes, you can just diff math
@@TechplantChannel What exactly do you mean?
@@matthiash.454 convert fahrenheit to celcius in the arduino code
I'm trying to make a incubator controlled by an arduino. But I want to control the humidity as well using the dht11 sensor. Could someone guide me to a similar video?
P.s: I don't want to use an lcd screen.
so would you be doing
the temp turns on and off the heater and the humidity triggers a fan?
You would need a 2 channel relay for that.
Can i use a dht11
Awsome
It made me relax when you added heat shrink I hate people who leave this shit exposed. I don't get it heat shrink is cheap so just buy it.
Although I would not have used a 150v fan I would have used a 12 or 9v DC fan
yeah i actually changed the entire thing to a 12v computer fan. much safer but the throughput sucks...
Do you have a similar set up with a humidifier and a colour display to read temp, humidity, date, time etc?
Subscribed
I will in the future. Right now i dont have space for projects but ill be buying a home shortly in which i will automate a lot of stuff so stay tuned.

How many temperatures probs can you add to one arduino
as many analog input pins as it has, i think you could do 8, they would have to share the voltage pins tho. you might have to do al ot more math. Im not really sure
I want to know how to use arduino pro mini instead of nano for this project
It should have the same pinout I'm not sure
Hi can I use it for my beehive what is the RPM of it
I think it would be way to high for a beehive, but you could use any fan in this setup just have to find a lower RPM. Would this keep your beehive cool in the summer? that sounds like a really neat project!
this video is really helpful and I will be grateful if am selected for the giveaway. I want to regulate the temperature of hot water inside a boiler tank that will trip at 75 degree celsius and pick up again when the temperature drops to 45 degree Celsius
Can I use light bulb instead of the fan? Does it affect the program if I used bulb?
Jason Fernandez sure you can hook whatever you want to the relay do you want the light bulb to turn on when it gets too cold?
@@TechplantChannel i was confused with the "serial9600" haha i thought it was only for the motors hehe. Btw, i want to use it as an incubator for my future poultry hehe thanks a lot from ph :)
I also might add LCD so that it would be more easier to monitor the temperature
can we use esp8266 as the board?
as long as it has analog pins for sensing the voltage then it should be fine!
Is it ok to use LM35 instead of that type?
I think so, but im not positive
Can anyone explain me the connection between sensor and arduino pins. The +ve of sensor goes to which point (A0, ref or 3.3)??
i havent touched this stuff for like 6 months so iforgot
im sorry.....
@@TechplantChannel I figured it out. Thanks
a year late, but nice video!
I plan to build a top hat and attach the fans to the hat so I can cool my dome.
Can I use arduino uno instead of nano ?
MANJUSHA JINESH yup the pins might be different tho
Any link to circuit diagram plz
sorry i didnt make one
What if I wanna just use the fan and the temp I wanna turn on the fan every 4 hours for about 10 min how would I do that
in your script youll just set a timer to turn it on every 4 hours and run for 10 min, it doesnt need the temp sensor. maybe ill make a video about this
@@TechplantChannel ok have to learn how to do that I'm new to this, thanks for the info
How many relays with different temperature settings can be run this way on one sensor?
like only one temperature sensor? you can run as many relays as you want to some extent, youd need a multiplexer. you could do like 8 very easily
Can I have a relay turn on at 40 off at 45 ( heat) then have a relay on at 55 off at 50 to open a vent then one on at 60 off at 55 for a fan. Exc. but just one temperature sensor. Multiple heating and cooling stages is what I’m after
@@benfriel12 yes you would just read from the same sensor and use some if statements in the code to check if the reading is in the range and activate the specific relay or relays you want only one sensor is needed for this
is this still work with arduino uno ?
yes
can I use LM35?
most likely the math might need to be changed tho
A common reference for a lot of this stuff is ‘tinning’
ahhhhh
Mine doesn't work ... My monitor keeps saying 535.42 degrees F
what if i will use a digital temperature sensor?
I think youll need some kind of digital to analog converter. If you have a raspberry pi you can use it with that, but youll have to wire stuff up a bit different
Ok sir
Build a switch to control a bathroom light due to my daughter always leaving it on. Instead of punishment I will give her a way to fix the issue.
Ard-reeno? 😅
if youve seen other videos of mine you will see quite quickly that pronunciation is NOT my strong point lol
You will never have 240 unless your bringing two hot lines in which you wouldn’t do with this kind of thing, your dryer and stove are 240 which is actually 208v so you don’t have to worry about that. Also regardless if it’s ac or dc it doesn’t mater what wire to connect the relay on AC doesn’t go in both directions current travels in one direction it’s about making a complete circuit. Dc can be switched on both the positive and negative, it all depends on if your circuit is sinking or sourcing
pwm
who the fuck is Fahrenheight? No flux for the temp sensors soldering? It will break off soon. Metric system is superior, btw.
The Imperial system is for intellectuals who can count by other numbers besides 10s.

OMG! @5:10 why do you cut towards your fingers with a razor! I learned not to cut anything in the direction of any of my extremities when my dad gave me a brand new knife at 12 years old.. (And extremely sharp) He promptly took it back when he saw my finger with its tip missing.. yeah yeah, say what you want, my dad taught me allot that many other dads don't even do. My point is, DONT make a howto video where you use a razor cutting towards your finger that is less than a inch away.
Bro please send me Circuit diagram
do something yourself you pighead
looks like a cannabis farm to me
