DHT11 Temperature And Humidity Sensor
dht-11
DHT11 is an inexpensive sensor that provides calibrated digital outputs for ambient temperature and relative humidity. It comes in a single row 4-pin package and operates from 3 to 5.5V power supply. It can measure temperature from 0-50 °C with an accuracy of ±2°C and relative humidity ranging from 20-95% with an accuracy of ±5%. It has got its own proprietary 1-wire protocol, and therefore, the communication between the sensor and a microcontroller is not possible through a direct interface with any of its peripherals. The protocol must be implemented in the firmware of the MCU through bit-banging of an I/O pin.

DHT11 Temperature And Humidity Sensor Module
DHT11
This is a very popular, ultra low cost digital temperature and humidity sensor. It uses a capacitive humidity sensor, and a thermistor to measure the surrounding air temperature. The result is available via a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds. But, for most applications this is not an issue at all.
