ر.س 25.00

The DHT11 is a basic, low cost digital temperature and humidity sensor. (How to use DHT11)

  • This is a single wire digital humidity and temperature sensor, which provides humidity and temperature values serially with one-wire protocol.
  • This sensor provides relative humidity value in percentage (20 to 90% RH) and temperature values in degree Celsius (0 to 50 °C).
  • This sensor uses resistive humidity measurement component, and NTC temperature measurement component.
