Abstract: An energy saving electricity control device based on microcontrollers was designed for intelligently controlling the power system of hotel. This device with the main-control chip of AT89C51 can control the public territory and guest room. Through the ingenious cooperation of photosensitive resistance, pyroelectric infrared sensor and stepping motor, the device can collect the messages of human body and illumination intensity. The new control device has the feature of auto power-off to save the energy after people leaving from the public territory and guest room.

Key words: pyroelectric infrared sensor, stepping motor, microcontrollers, energy saving electricity
