Just received my Xiao logger hat and connected to a Xiao ESP32C3. I’m running Micropython and am only interested in ambient temperature. The SHT40 is reading about +4C above my thermometer at room temperature. I was expecting to be within at least 1C. At first I thought it might be the board temperature, but there is a hole in the sensor to allow for air to enter.
I’m suspecting either a factory calibration issue (Sensirion) or damage during board assembly. Anyways, let me know if you are not seeing the expected temperature on your Xiao Logger board.
I have used at least 10 different Adafruit MCP9808 boards for 4 years now and they have been very accurate (within 0.5C) and reliable. I was hoping for a more compact temperature measurement setup with the Xiao Logger, but +4C at room temp is a big let down.
Thanks.
