Arduino Uno Wifi Temperature Sensor

[@thedude8046]

Been looking for this for a while

[@acestudioscouk-Ace-G0ACE]

Thanks for this, it was very clear and easily understood by this non techy guy from the arts!

[@frankneufeld1667]

How would you connect multiple temperature sensors?

[@nikolaygorashchenko9979]

Thank you so much! I've just changed the code a bit to use a digital temperature sensor (DS18B20) and Bob's your uncle! It's working!!! Great!!!

[@hezro7128]

Hello, I tried to develop a similar application using the DS18B20 sensor but it doesn't work for me. I can read the sensor with the Arduino UNO, but not with the Arduino UNO Wifi REV 2. Can someone help me?
with the arduino UNO wifi I only read -127

Thanks for teaching awesome stuff, Eli. Been watching for years to get into IT.

For the voltage drop and easy math you could have used external voltage reference on the AREF pin. That way the calculations would have had the correct voltage levels each time.

[@neillervick447]

I am very new to coding, I would like to modify this so that it reads and displays the status of a switch. How do we adjust the displayed message in the browser?

[@MrChasekennedy]

eli, you know you can offer a 5v reference right?? external references are important to any adc project to get any real accuracy. bandgap reference or there are temperature compensated references available at fairly cheap prices. for this you could have referenced an lm7805 even and been closer. relying on the arduino reference is often not a good idea as the arduino dev boards dont have the best voltage regulation. one other trick is sampling the input voltage and using that value to adjust what your readings are in program.

Could you tell me how to make the web browser auto-refresh?

[@chomik2905]

Hello, I have a question. I use Arduino UNO Wemos D1 instead of Rev 2. I wonder why my ESP8266 doesn't give me IP and it can't connect, still trying.

[@waynereeves4723]

Concerning the Arduino Uno Wifi Temperature Sensor: Is it possible to access the temperature reading from outside your home network?

[@seanobriain5650]

Does anyone know a reason why this code would be stopping an output i have included with this code

[@MarsTheProgrammer]

Question... instead of hard coding the ssid and password, is there some way to send it from a phone/app?

[@charmillesrepair708]

Hello nice work how can we control this unit remotely from cell phone
Is there a solution to send instruction to the arduino remote ....thanks 👍

[@horanneo3105]

Many thanks for posting this tutorial. Can I ask why I cannot see the data from the web browser whist the serial monitor reviewed I should? I also used client.print( ) and client.println but there is nothing displayed

[@horanneo3105]

Ok, I have just sorted it out. You should never consider yourself using a local network when the VPN is on :) Turn it off and everything is fine.

[@skhumbuzocele1330]

You just needed to put the actual voltage in your code that you have in your board to calibrate the temperature, in your case it was 4.8 volts!

[@2Can-Dan]

Hey, I love your videos.
Would you be able to do a tutorial to connect a standard R3 non-wifi Uno to an esp8266(esp-01s) and dht22 to view on a webpage as well? Cheers. :)

[@atom_zero5413]

I came from your secundary channel. I HAD to see it to believe it. 907 views from 949K subs. I never seen anything like this. Defies logic. Hang in there.

[@karenrosas7974]

Hi, your tutorial is amazing. I tried to use a different sensor, a BMP180 but I have a problem, the sensor didn't start to read the temperature. I taseted the senosr in a normal arduino uno and it works perfectly, the problem is that in the arduino uno wifi doesn't work and I don't know what to do :c

[@martinkokaua4590]

Hi There, am i able to connect multiple sensors to one board or do i need one board for each sensor. Cheers

[@thedude8046]

I wanted to know that too, I want to make one for in and outdoor measuring.

[@gastonboucher3331]

doing this project on 12/17/2021 and wifinina is terminated?? is there any alternative or fix to this issue, love the content keep it up!

[@syyhuuchan9171]

can this temperature sensor accurate for human use?

[@dcpowered]

Thanks a lot for making this Arduino series of videos. Much appreciated! Could you also explore the new Arduino Nano 33 IoT and BLE boards?

[@mdd1963]

another Arduino video absolutely pertinent to the 12 folks (globally!) interested in... Arduino! :)

[@mdd1963]

yayyy, first! :)

[@Risky-fm3ng]

Thank so much for reference... appreciated

[@ΤΟΝΙΑΧΡΙΣΤΙΔΟΥ]

Hey man it would be better for us if you given lessons on how to use chips like esp8266 to connect arduino to wifi the implementation is harder but its a low cost solution since arduino-wifi costs too much !

[@awakening_bryan]

That's why you buy arduino components by the dozen

[@patlaroche608]

VERY Thanks!

[@KameraShy]

If you use battery to power the Arduino, its voltage will decrease as the battery drains.

[@jpthedelawarebeeman6239]

Hello there - I have built 3 of these sensors using a Wemos D1 mini and a 10k thermistor with a 150k resistor - it works but its in Celsius and I prefer Fahrenheit can someone please help me with changing the code or point me somewhere that would have the code or help me change it. Thank you - It also has a fast refresh rate where in the code would I see the refresh rate to make it refresh slower say a minute or 5 minutes? Thank you again

[@ac4cars656]

Excellent

[@thenottakenone]

thanks

[@ahmedsamikhateeb]

My Arduino UNO wifi gives me exactly 5 V

[@patlaroche608]

VERY Thanks!
