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). Temperature and humidity sensors are used in a variety of industrial applications for controlling the motor pumps and auto cooling systems.
- Senses both Temperature and Humidity
- Used with a variety of microcontrollers
- No external analog input reference pins needed
