Temperature Not Reading

Mon Apr 10, 2017 3:04 pm

So I got a temperature sensor that is a DHT22 and I am using https://github.com/adafruit/Adafruit_Python_DHT for the reading. This is the code I use https://github.com/adafruit/Adafruit_Py ... ruitDHT.py. I run it in the terminal starting with cd Adafruit_Python_DHT/ then cd example/ python AdafruitDHT.py 22 17 because that is where it is but every time it says to retry. I have triple checked everything. Anybody know how to fix this?

How have you connected the DHT22 to the Pi?

http://abyz.co.uk/rpi/pigpio/examples.html#pdif2_DHTXXD will work if the DHT22 isn't bust and if it's connected properly.

I think Joan wants a real-world photo of your physical wiring, not a picture of your theoretical wiring done with Fritzing.

Most of us know the theory of how these things need to be wired, if we're going to help we need to know whether theory matches reality.

Ok. I'll get an actual photo
