Arduino Advent Calendar Day 13 - DHT11 Temperature and Humidity Sensor!
Today we've received from a DHT11 Temperature and Humidity Sensor.
The DHT11 is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesnâ€™t require extra components so you can get right to measuring relative humidity and temperature.
The DHT11 sensor uses a proprietary 1-wire protocol. We'll need to install an Arduino library (the SimpleDHT library) to make use of this sensor.
Enough talking about it let's go and build up the circuit over at guides.littlebird.com.au .
