Humidity Sensor and Digital Temperature Module AM2302 is a basic, low-cost digital temperature and humidity sensor.
Humidity sensors work by detecting changes that alter electrical currents or temperature in the air. A capacitive humidity sensor measures relative humidity by placing a thin strip of metal oxide between two electrodes. The metal oxide’s electrical capacity changes with the atmosphere’s relative humidity.
