Sensors / Humidity

Humidity is the concentration of water vapor (water when it's a gas) in the air. Some places are humid and make you feel soggy and hot like you're in a sauna. Other places are dry, which makes it easier to get nose bleeds and static zaps. Equipment, plants, humans, cigars and musical instruments all are affected by humidity.

We carry a gamut of humidity sensors, whether you need something basic and low-cost like the DHT22, weatherproof outdoor solutions like the SHT-10 Mesh-protected sensor, or STEMMA QT plug-and-play sensors like the Adafruit HTS221 - Temperature & Humidity Sensor Breakout Board.
