The DHT11 is a humidity and temperature sensor that produces a calibrated digital output signal. The DHT11 can be connected to any microcontroller such as Arduino or Raspberry Pi and provides instant results. The DHT11 is a low cost humidity and temperature sensor that provides high reliability and long-term stability.
Capacitive humidity sensor and thermistor are used to measure the ambient air and output a digital signal to the data pins (no analog input pins required). It's very easy to use and you can use the Arduino and Raspberry Pi libraries and sample code.
This module contains the pull-up resistors required to use the sensor, making it easy to connect the DHT11 sensor to an Arduino or microcontroller. To use the sensors Vcc, Gnd, and Output, you only need to make three connections. Thanks to
's unique digital signal detection technology and temperature and humidity detection technology, it has high reliability and excellent long-term stability.
