Hello,
In my project, I am using BME280 sensors along with Arduino to monitor the humidity and temperature of an indoor farm. Currently, I have 10 BME280 sensors in my inventory. These are from Adafruit. For description, this is the link.
The issue I'm facing is - all 10 sensors are showing relative humidity 10% to 12% lower than the actual humidity.
I am cross-checking the humidity values with actual dry-wet bulb hygrometers and also handheld digital hygrometers (link). All these devices show humidity 8% to 12% more than BME280 sensors.
Can anyone help me to fix this issue?
Thanks,
Aditya Ponkshe
