I would like to use the MLX90640 far infrared thermal sensor array on a car as a "night vision" camera. Since glass blocks thermal radiation I have to install it outside the cabin. Is it possible to make the sensor waterproof while still keeping its thermal sensitivity?
I know that water blocks IR so there will be no thermal imaging when the sensor is wet but the idea is rather to protect the sensor from damage and wait till it dries out for further imaging.
I think there may be 2 ways to protect the sensor:
- waterproof coating
- waterproof housing
Unfortunately I have no idea on practical realization of either of those.
