Hello, I can use BME280 in industrial application? I'm need monitoring refregerators, what you mean, this device work correctly long time at -20 deg?
Sensor working condition is -40 -85 degrees.
So for -20 degree our BME280 is working correctly. please also pay attention on page 9 figure 1 in the datasheet of BME280 about the sensor operation range.
what you think, how this work if temperature be below - 40 degrees?
If temperature is lower than -40 degrees, our sensor is not guranteed to be working correctly.
