- Learn how to connect the DHT11 and DHT22 Temperature & Humidity Sensors to a Raspberry PI and Arduino. We cover all the connections for both sensors on both hardware platforms as well as provide and review the code to get them working!
Check out the Github page for all of the code we used, pinouts and connection diagrams.

thanks! this is very helpful!
Great video .Easy to follow and well explained thankyou
I got this error:
File "dht22.py", line 31 print 'Temperature: ({0:0.1f}C) ({1:0.1f}F) Humidity: {2:0.1f}%'.format(celsius, fahrenheit, humidity) ^ SyntaxError: invalid syntax
How do you display the timestamp on the recorded data temp?
Your code is so clean! If I had these at home, I'd be able to follow along no problem.
Is the main use of these to put inside computers or something to make sure they don't overheat/ nothing's wrong?
Thanks! Sure, that would be a decent use for these. I've also used them for monitoring ambient temperature in the house, monitoring the temp & humidity of my 3d printing filament etc. They are best for scenarios where you are measuring ambient areas. There are other temp sensors that that are good for isolated measurement, for something like monitoring the temperature of beer while brewing, cooking, coffee roasting etc. I am going to cover those in the future as well.
@@makersdigest4752 are you using some kind of broker to gather the data? Mosquitto? did you made a video about it
Great vid do you think it would’ve possible to do this with multiple sensors giving an average with a wireless network connecting them to the pi?
someone know why i have an error saying : No module named adafruit_dht
i have already install Adafruit_dht ...
if someone can help me it would be very nice !
Hello, can you please elaborate on why you use this "pull-up resistor"? I don't understand what it is for, as it seems to bypass the sensor? Thank you in advance. I just found your channel and it will help me a lot in my current project.
I am sorry I figured by myself. There are plenty of tutos on what is a pull up resistor on youtube.
The code is full of syntax errors. I worked through them and got it to work though.
I'm running into the issue where the script is pushing the same temp, humidity over and over again - but when I cut, and rerun python file.py then it'll update the values, anyone know why this might be?
Cannot read your program on the screen, too small letters.
