Hi,
I made two weather stations, located in two different cities using BME280 sensor for reading temperature, pressure and humidity values.
When the sensor boards are new all values are good, but after one or two months, humidity values begin increasing. After one or two more months, humidity values are allways over 100%. The only solution is to buy new sensor boards, and the problem repeats again.
I bought sensor boards from different manufacturers but all with the same result.
These boards are very simple. Only contain the BME280 sensor, some resistors, some pads to select I2C address, and the I2C connector.
Thanks for your answers.
