This project demonstrates how to use a DHT11 humidity sensor with an Arduino Uno to measure the relative humidity in the environment. The sensor provides digital output that is read by the Arduino, ...

Humidity Sensor (DHT22) The DHT-11 (also named as AM2302) is a digital-output, relative humidity, and temperature sensor. It uses a capacitive humidity sensor and a thermistor to measure the ...

Use a sensor with a probe to control the temp and humidity in a beer fridge, cheese or charcuterie cave, or just to monitor an exterior fridge or freezer, receiving alerts if they go out of a set ...
