Yes.
You’re right.
Maybe you have defective sensors??
It’s either that or bad wiring.

Hi Sara
Sensor is labelled AM2302 which should correspond to a DHT22 I believe

Hi.
Do you really have a DHT22?
Isn’t it a DHT11?
Regards,
Sara

Pulling my hair out here
Trying to get a Temp Humidity sensor working for a project t MIT
I wired it all up per the website
I keep getting
“Failed to read DHT sensor”
I tried 3 different DHT22 sensors
I tried changing V to 5 volts supply to the DHT22
I tried changing GPIO pin from 4 to 6
I tried removing the 10k resistor b/c people say its built in to the DHT22
I tried changing baud rate from115200 to 9600
I tried using previous versions of DHT library
Nothing worked !!!!
Would love to hear how to get this thing working
Best
Jay

After reading it always returns NAN
After several attempts I do not find the solution.
