How about old school wet bulb / dry bulb with a chart something like this: https://www.amazon.com/Taylor-Precision-Permacolor-Mercury-Free-Hygrometer/dp/B002E0EH3A
Low maintenance, no batteries and no calibration necessary; just use distilled water to keep deposits to a minimum

micksmelanie:
a model sold on aliexpress
