Abstract:
    An intelligent electric-saving switch can identify moving direction of human bodies. The intelligent electric-saving switch comprises a microprocessor MCU (1) as the key part, one or a plurality of infrared emission pipes (2) and a plurality of infrared receiving module (3) as human body sensors, a photosensitive resistor (4) as a luminance transducer and also push-button switches (5) (6), an output control switch (7), a displaying light-emitting diode (8) and a direct current power supply (9). The MCU transmits infrared beams through the infrared emission pipe and the infrared receiving module detects the signal reflected from the human body to the MCU. According to the sequence of detected signal from the infrared receiving module in different positions or exits and entrances, the intelligent electric-saving switch judges moving direction of human bodies and whether there are people in doors. The power is turned on or off through a controllable silicon or a relay with detected brightness of the environment and working mode. Simultaneously, the power switch can be controlled by hand. This apparatus actually has the effect that the lamp is turned on with people, off with nobody, on with requirement and off with no requirement. The intelligent electric-saving switch saves electricity and is convenient and practical.
