Hi I was at Anoka today,great work very informative big like and added keep in touch thanks ❤
Thank you.
that click at the beginning literally reset my brain
didn't get you
This sounds like what I want to do, but it depends upon this Arduino cloud. I would like to measure 5 rooms in a house along with one outside unit using wifi, but not with an internet connection. I want to graph them over time on one chart.
Nicee
Thanks. Please subscribe.
thank you so much
Welcome 😊
thank you
You're welcome
If the router tells me that it is connected but the IP address does not appear on the serial monitor, but the MAC of the device appears linked, I am connecting the ESP 32 with a WLAN 1100 (PHOENIX CONTAC) in the web administrator (of the wlan) It tells me that the ESP 32 is in the connected devices and it gives the MAC, but in the serial monitor it only shows points, that is, it stays in the while and does not show me the IP address, what could I do?
To connect the WLAN with a tablet or a mobile phone, I must configure the IP to be static, enter the data and it connects, how can I do it on the ESP 32? That is to say, it would be to put the data on its own IP address, WLAN IP, "prefix length" dns 1, dns 2, how can I assign (program) these values to esp 32? What strategy do you recommend?
Would I be able to set one of these up in my van to check the temperature inside and let me know if it goes about a certain temperature? Would I be able to text the monitor and receive the info too?
Hi sir, how can we connect 6 sensors on single iot app to monitor temperature & humidity at 6 different locations ?
This is cool
Thank you.
I need a help from you how to contact you
please connect me on facebook facebook.com/techtrendsshameer
Thank you so much for this video
Is it possible to add an battery voltage sensor along with the temperature sensor in the same Arduino, How can we combine the both program codes
Yes. Possible
I'm just getting nan values. Using a Wemos D1 Mini and DHT11
I've got this running on a sensor for a greenhouse, but the battery keeps draining and never recharges with the esp8266 plugged in(charges when esp is unplugged) could anyone help make a timer loop so it only reports every 10 minutes, and enters ultra low power mode at say 11pm until 9am, any help would be greatly appreciated
You can add a delay in void loop() section
Hi Great Video, but i have some problem with the data output.
I have a ESP8266 D1 and was able (after fixing a lot of other problems) to verify and upload the code.
I think the device is online, because on the router overview i see some esp with an IP adress. I cannot ping it, but i think this is not a problem and just not enabled. The hardware is fine, because i tested it with some normal arduino IDE sketch.
The Problem now is, that i dont see some data on the dashboard. Also when im in the Cloud on ,,Things'' and click on my device, the status is Offline. Maybe this is a Problem.
The sensor is a DHT11 with the light is on and the signal Pin connected to Pin 2, but i also tried with pin 4. (also with change the number in the code). I think this is also fine.
Some ideas, why i cannot see he value in the dashboard?
thanks in advance
Can you please check the serial monitor whether it is display any data ?
I have a problem with a BOARD "ESP32 WROOM 32" shows disconnected even though it is connected to the computer. and I want the code of dht22
What protocol is used in this project?
HI , I has faced a dht reading "NAN" reading on messenger, although dht11 reading on arduino examples is OK. Anyone could help would be appreciated very much.
I am getting the error message "Serial Monitor Unavailable". Did all the steps as mentioned... But the Dashboard displays two dash ( -- ) in the Temperature and Humidity Graphs
hii .. i have been following this video step by step but my code has been uploding but it showing me hard reseting via RTS pins and then not showing any results on the graph . can you guide me please
Hii sir you can add the gas sensor and relay connected with axial fan using the esp32 lpg gas leak program please sir
👍
Thank you.
@@TechTrendsShameer source code, please....hehehe
Please check the video description for the source code.
Sir no change in dashboard it is showing in arduino editor monitor screen but not in dashboard pls help
hello Sir if want to get alert call or mesg on the mobile what should we have to do
Sir we are not getting values in dahsboard sir but we are getting in serila monitor we checked all our varibale its all the same name can plss help us sir
Can you tell me the application that where it can be used
Thank you soo much sir
But sir can we do this project without ESP8266...
And Can we do with only DHT11 and Arduino ??
Yes we can do. I did a video. Please check my channel.
Why is dht pin set to 2 if you use d4 in nodemcu? shouldn't it be 4?
That is based on the pin confuguration of ESP8266. Please check the pin diagram of ESP8266
Sir wonderful video...but there is no change in the temperature and humidity meters and graphs...though we get values through serial monitor....
Assume that you can reply...sir..please give a kind reply..
No change in dashboard values sir......
You might have gave the variable names different. Please follow the full video and gave the same names.
@@TechTrendsShameer Given the same name, yet there is no change in gauge meter and chart. Hope, you will reply.
May I know what error you are getting?
@@TechTrendsShameer Troubleshooting done, googled. Now, working.
There are lot of folder in source code file ,just be clear about the coding side because its the important one all need don't rush in that part
Those file and folders will be generated automatically by Arduino IOT Cloud. Please follow the steps as mentioned in the video
can this app send notifications/alerts when temperature or humidity exceeds a particular value?
We can send email, but that option is paid in Arduino IOT Cloud.
How do i get the temperature reading in Farenheit?
Use this formula °F = °C * 1.8000
Can I use a separate temperature sensor and a separate humidity sensor instead of the two-in-one sensor?
Yes. You can.
@@TechTrendsShameer Thanks for the answer. I have one more question and that is, can I send a text message to my phone(or 2 phones) when the temperature goes above or below a set value?
@@macvideoworld have you had any joy with this?

i tried uploading the code its says executing command=exit status 2.wheres the problem?
Send me the full error message.
I've done everything as shown but I only can see the values on the monitor not on the dashboard... what am i doing wrong?
Can you check the variable names are correct?
I want to setup automatic temperature and humidity monitoring for my vermicompost production, need some help.
Tell me.
I am not able to find right kind of product in market. Need someone who can make custom product as per our need.
There is error uploading while slecting the board and port ? How can we resolve this????
port is showing in your laptop?
Thank sir, is any issue if we connect 5 volts sensor with ESP8266 which 3.7 volts
No issue. you can connect.
@@TechTrendsShameer thank one question if you do private projects
Is there a way to set it up to read Fahrenheit
Please use this formula and calculate.
° F = ( °C × 9 5 ) + 32
Sir thanks for this video... But .... Is it give messages (sms) to mobile? Sir we got output as temperature and humidity values.. But can i know, is it gives sms to mobile?
Waiting for your reply sir
No. This experiment won't sent SMS to mobile. For that you need to add GSM module.
@@TechTrendsShameer sir can can we use 4g sim for any gsm module... Sim 800,sim900a , sim800l... ?... Please sir tell about it..
Yes. You can use.
I keep getting "collect2: error: Id returned 1 exit status" and can't figure out what I did wrong

Please follow the same steps as mentioned in the video. Also check whether the board connected to the port correctly.
Is there any way to make it without wifi using gsm
Might be possible. Haven't tried that.

Hi ... I workout the process but I have one error will you share the solution ... Humidity was not declared in this scope plse share the idea....
Humidity variable is declared. Pls watch from 1:54
Good evening sir may I know where to get the thingid
Thingid is not needed. You will get the device id and secret key from the arduino iot cloud website
Does this need an internet connection to operate?
Yes
Can I use DHT22 instead of DHT11. Will it be the same code or different code?
You can use. The code will change. Instead of DHT11, need to use DHT22 in the code.
@@TechTrendsShameer Will I only change the DHT type in the code or anything else because after changing the DHT type, still the temperature and humidity is not displayed in the dashboard. Can you please help with the code
Nothing else will change. Please contact me in instagram.
Please send the code. I also have a dht22 sensor and it doesn't work in messenger it is marked nan send you the code for a dht22 sensor
Does it work the same with dht22
Yes. It will work. One line of code need to change

if I want to use one dashboard that can be controlled by many let's say 5 people ...if person A turn on the LED the next day Person C turn On the same LED...how do I make it ...if I have to share a password with others but how do I know that person C turn it on ...
You need to share the password. That's the only option. You can monitor the dashboard in mobile, whether the LED is ON or OFF once the person turns it ON/OFF.
morning ...hye i am nur syah from Malaysia..actually I want to design a system that able to control the LEd by many ...i mean if Mr.A turn the LED 1 then a few hours later Mr.B turn LED 2 ...but how do I know who and whom turn it On Or Off The LED 1 or LED 2 ...is there I can see data save somewhere@@TechTrendsShameer

Can you help me for do this project
Sure. Will do
Why do I get NAN values?
Might be two reasons.
1. Please check the pin which you connected and the pin mentioned in code is same.
2. Please check which sensor you are using dht11 or dht22
@@TechTrendsShameer Thank you for your answer. The pin layout is OK, I am using a Dht22. #define DHTTYPE is set to DHT22.

Jumper Wire.
Hi Sir, how about if you want to put a buzzer too, if the temperature is really high!how to do it?
Need to modify the code and circuit.
Can i use thermocouple k type with MAX6675 as temperature sensor?
Yes. But need to modify the code.

@Tech Trends Shameer look at the time after you uploaded the code and you go to your dashboard at 9:04 you can cleary see the time is in 9:57 and no measurement for temp and humidity then suddenly it has and the time skip to 10:01 it should be real time when you uploaded the codes do your tutorial properly lols
Its real time video only. Instead of posting a long video, I just trimmed the length and showed the temp at different intervals.
sir can we get a report for this project
Yes. I can provide
may u please provide us report and synopsis sir
Sir l am getting Nan value and instead of writing code for led it's not glowing on and off when I use switch dashboard also. And thus there is no change at dashboard
Please give the correct variable names
Sir actually l got all the values even my serial monitor is displaying all the values but my led in not glowing and dashboard is stuck at the values of 33 and 36.3 of temperature and humidity respectively, it doesn't get changed
The program which I wrote is to display temp and humidity. Did you add the code to glow led? To change the temp, humidity values, place the sensor near any hot object.
@@TechTrendsShameer yes sir l wrote the code for glowing led also
Ok. You might be missing something in the code.
Can u sent the coding copy
Please check video description
Can u please send me the code for the program
Please check video description
why don't you provide entire code properly for users... this is for reference only right..???
I think you didn't checked the video description.
error is occured -temperature is not declared
