I've a problem with Weather Board 2's BME280 sensor. The shown temperature is at least +5°C higher than in reality.
I use Odroid N2. Weather Board 2 is connected to I2C-2. I use 50cm long jumper wires, so the WB2 is afar from the potential heat source. It has no Sun contact.
Output at the moment:
Code: Select all
UV_index : 0.01 Visible : 103 Lux IR : 77 Lux ======== bme280 ======== WEATHER-BOARD v1.6 temperature : 26.48 'C humidity : 58.36 % pressure : 984.75 hPa altitude : 330.533478 m
What's strange, when the temperature was higher (29 °C in the room) it showed only +1 °C higher (30 °C),
I could set an offset (delta_temperature) in Home Assistant, but this measure differs depending on temperature, so -5 °C delta wouldn't be good in all cases.
What can I do to improve it? I'm totally new at single board computers, so any, even obvious tips would be welcome.
