DHT – 11 Temperature Sensor With Cable


  • DHT11 digital temperature and humidity sensor is a calibrated digital signal output temperature and humidity combined sensor, which utilizes exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability.
  • The DHT sensors are made of two parts, a capacitive humidity sensor and a thermistor.And with a high-performance 8-bit microcontroller connected.
  • Small size & low consumption & long transmission distance enable DHT11 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient.
  • The sensor is a calibrated temperature and humidity combined sensor and doesn’t require extra components so you can both measure relative humidity and temperature.
  • The digital signal is fairly easy to read using any microcontroller.
