Product details
The DHT11 is digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and outputs a digital signal on the data pin (no analog input pins needed). It’s very simple to use, and libraries and sample codes are available for Arduino and Raspberry Pi.
