DHT11 is a popular Temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). It comes in a module to easily use with the Arduino and other microcontroller boards. Temperature and humidity sensors are used in variety of industrial applications for controlling the motor pumps and auto cooling systems.
- Easy to use with Arduino
- Senses both Temperature and Humidity
- Used with variety of microcontrollers
- No external analog input reference pins needed
