I purchased a BME280 Humidity/Environment sensor from DFRobot BME280.
I will need to monitor humidity inside of a bin that can range anywhere between 60-95% humidity (possibly 100%). I plan on putting the microcontroller inside of a weather proof polycase Polycase Enclosure
I'll have some wire glands that run to the actual BME280 sensor. What I'm not sure of is how I should best protect the humidity sensor. I'll be growing some mushrooms so I want to try and avoid any strong chemicals, but I still need to expose the sensor.
I considered purchasing another small polycase (cheaper one that's not weather proof), enclosing the sensor inside of that, coating the entire board with clear nail polish with the exception of the actual sensor, and then drilling some small holes on the polycase.
Do you guys think that will work well given the humidity is pretty high?
