A capacitor type of hygrometer is usually used to measure relative humidity. The sensor has a dielectric polymer layer that absorbs water molecules from the air through a thin metal electrode.

Seeking data on how well the appliance works, [Matthias] wired a DHT22 temperature/humidity sensor to a spare Raspberry Pi to monitor room conditions, and plugged the dehumidifier into a Kill-A ...

The development of biodegradable paper sensors for temperature and humidity by Auburn University researchers enhances sustainability in agricultural monitoring.

The sensors proved reliable and sensitive to changes in temperature and humidity levels. They successfully detected changes in relative humidity levels from 20% to 90% and temperature variations ...

Emerson today launched its new AVENTICSTM DS1 dew point sensor, the only industrial sensor to monitor dew point, temperature, ...
