I am experiencing wrong temperature and humidity readings when using a D1 mini (ESP8266) to read a DHT22 sensor.
Temperature is 2 to 4 degrees higher than real and humidity is 15-30% lower.
The sensor is placed away from the ESP8266 so no heat from the processor distorts readings.
I have tried different units of DHT22 and all give me the same result.
I also tried an arduino nano with these sensors and with the nano it works ok. with the same DHT22 units, readings are good.
I used the same libraries for DHT readings with nano and D1 so the only thing different is the device (D1 mini vs arduino nano). Do you have an explanation of what could be happening here?
Thank you very much in advance!
