The DHT11 Temperature 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 Sensor 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 Temperature Humidity Sensor 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.
