A humidity sensor (or hygrometer) senses, measures, and reports both moisture and air temperature. The ratio of moisture in the air to the highest amount of moisture at a particular air temperature is called relative humidity. Relative humidity becomes an important factor when optimizing for human comfort.
These BOSCH BME680 sensors are fairly simple to use, pre-calibrated, and don’t require extra components so you can start measuring relative humidity, temperature, barometric pressure & approximate altitude fairly quickly.
