Raspberry Pi Asked on October 5, 2021
I have configured the RPi to read value from the DHT 22 sensor. I have used AdafruitDHT library but when I start AdafruitDHT.py script I got totally incorrect value e.g. “Temp=537.7* Humidity=1152.0%”
I have to say that I made a mistake in the first wiring (I connect the data pin to 3v3 Volt of the raspberry and power supply pin to GPIO of the raspberry).
Did I fried the sensor making incorrect wiring?
Thanks

If you get any readings at all it is probably wired properly.
I suggest you try my DHT Python script.
Leave the module with the name DHT.py and then issue the following commands in the same directory.
sudo pigpiod
python DHT.py x
Where x is the (Broadcom) number of the GPIO connected to the DHT22 data line.
