Today I have ordered DHT11 in ebay.Just need to do some experiment with GPIO pins on Raspberry Pi in input mode.
DHT11 Temperature and Humidity Sensor features a calibrated
digital signal output with the temperature and humidity sensor complex.
Its technology ensures the high reliability and excellent long-term
stability. A high-performance 8-bit microcontroller is connected. This
sensor includes a resistive element and a sense of wet NTC temperature
measuring devices. It has excellent quality, fast response,
anti-interference ability and high cost performance advantages
