Tianlong, N. (2010) Application of Single Bus Sensor DHT11 in Temperature Humidity Measure and Control System. Microcontrollers & Embedded Systems, 6, 026.

For DHT11 sensor, the decimal bytes of temperature and humidity measurements are always zero. Therefore, the first and third bytes of received data actually give the numeric values of the measured ...

He decided to take an in-depth look at the DHT11 sensor; which you can get your hands on for under $3 if you know where to look. The four-pin device uses a 1-wire protocol.
