Interfacing a DHT11 humidity and temperature sensor
Raj show how to interface his PIC16F breakout board with the DHT11 humidity and temperature sensors. The DHT11 uses a proprietary single-wire protocol, not Maxim’s 1-Wire (which we consider EOL).

This articles discusses the DHT11 sensor which also provides calibrated digital outputs for temperature and humidity but is relatively lot cheaper than the Sensirion sensors. The DHT11 sensor uses a proprietary 1-wire protocol which we will be exploring here and implementing with the PIC16F628A microcontroller that will receive the temperature and humidity values from the sensor and display them on a 16×2 character LCD.
