The DHT11 temperature and humidity sensor is a low-cost and easy-to-use device for measuring ambient temperature and humidity levels. It uses a capacitive humidity sensing element and a thermistor to measure the relative humidity and temperature, respectively. The sensor outputs a 16-bit digital signal over a single-wire interface, making it simple to use with microcontrollers such as an Arduino. The DHT11 is commonly used in a wide range of applications, including home automation systems, weather stations, and HVAC control systems. It is not very accurate compared to other temperature and humidity sensors, but it is still a popular choice for its low cost and ease of use.
Aosong DHT11 is factory-calibrated and communicates with a microcontroller over only 1 digital I/O pin

The sensor is very easy to connect, and a library and example code for Arduino is available following the download links below.

  • Operating Voltage 3.5-5.5V
  • Current Consumption Measuring 0.3mA.
  • Current Consumption Standby 0.06mA.
  • Sample Time min. 2s.
  • Dimensions 14 x 31 x 8 mm, 2.6g
