wie kann ich 2 DHT22 mit einem Nano integrieren?

@techathome Жыл бұрын

In the code comment definition of dht11 and uncomment #define DHT22. But u need to replicate the code for one more sensor

Connection might be wrong. Check 5v and Gnd connections to the DHT.

Check the connections. Your sensor is not giving any values to Arduino pin

Check the code there it is written line no 10 uncomment whatever you are typing There #define DHTTYPE DHT11 should be there.not DHT 22.I mean change the line no 16 from DHTTYPE DHT22 to DHTTYPE DHT11
