It will be best if the sensor is connected 5-10cm away from the device. The sensor connected directly to the connector will be heated by the device through paths and goldpins and you can not help it.

As far as dht11 / 12 is concerned, I already subtract these 2-3 degrees in the program from the read temperature, which are overstated. But you have to check it yourself experimentally if the result is overstated with any other sensor in the temperature range you want to measure.

Unfortunately, I don't have dht22, so I won't tell you anything specific about its accuracy or results.

This is something I also find quite bizarre, and is an issue with the new M5Atom also.
the address should be 0x68 but on using the i2c scan program on m5atom which also has an mpu6886 no addresses are found. then I found this in the arduino header file which puzzles me.

void setup() { M5.begin(true, false, true); if (M5.IMU.Init() != 0) IMU6886Flag = false; else IMU6886Flag = true; }

why should it's address be zero. It seems like this code works in arduino in the case of the M5Atom but I cannot find a workaround for micropython.
