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.
