DHT11 /DHT22 Temperature Sensor -

The DHT11 is a 4-pin (one pin is unused) temperature and humidity sensor capable of measuring 20% - 90% relative humidity and 0 to 50 °C. The sensor can operate between 3 and DC and communicates using its own proprietary OneWire protocol. This protocol requires very precise timing in order to get the data from the sensor.

DHT11 temperature-humidity sensor

DHT11 temperature-humidity sensor. The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data.
