Medium Precision Temperature and Humidity Sensor DHT11 with 1-Wire Data Bus, for microcontrollers like Arduino, Raspberry, and others.Aosong DHT11 is a calibrated, integrated humidity and temperature sensor, and it communicates with a microcontroller over only 1 digital I/O pin. The sensor provides a 16bit resolution, takes only about 0.3mA (0.06mA in standby), and needs a power supply in the range of 3.5 to 5.5V.

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
