An Arduino project to display DHT11 temperature and humidity readings to an LCD screen. This layout uses a three-pin DHT11 (specifically this one). The Adafruit DHT Humidity & Temperature Unified Sensor Library helps read the temperature and humidity data from the single digital read pin.
This project is also available on Arduino Create.
