DHT11 Basic Temperature Humidity Sensor Plus Extras

DHT11 Basic Temperature Humidity Sensor Plus Extras

Adafruit Industries LLC

The DHT11 is a basic, digital 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 is simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using the library, sensor readings can be up to 2 seconds old.
