Ondrej Karas of DoItWireless writes: This article describes temperature and humidity measurement with DHT11 sensor connected to TR module. Circuit diagram is very simple. You need only power supply for sensor and one wire for data line. This line has to be “pull-uped” – sensor has open colector output.

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. […]
