Hi all,
@robalstona have you found a fix ? also i have the same problem and i would like to know if i need to use ENV Hat / ENV Unit / DHT22 Grove to have a good measurement

Hi ajb2k3,
thanks for your response.

I found this thread that explain issue M5 Stickc Arduino samples - Temperature reading issue

but i can not find any thread that report some solution, could you help me ?

Hi all,
i trying to compare measurements (temp/humi) from DHT12 into ENV Hat and DHT22.
I used a DHT22 attached to an ESP32 and ENV Hat attached to M5StickC and this is result

i haven't an external meter to check the right parameters, but seems that DHT22 measurements are more realistic.
Is possible that measurements of the DHT22 into ENV Hat are so far from the real ones ?

may I have been wrong to call the functionality ?
For DHT22 i copied DHT12.h and DHT12.cpp from example and use in my project as follow

DHT12 dht12;

setup() {
    M5.begin();
    Wire.begin(0,26);
    ...
}


loop() {
    ...
    float actualTemp = dht12.readTemperature(1);
    float actualHumi = dht12.readHumidity();
...
}
