<p>An automatic power-saving control device is provided to sense a moving object by using a micro controller which adopts an individual program with thermal sensors and infrared sensors in an electrically lighting place, thereby automatically turning on/off an electric lamp. Thermal sensors and infrared sensors(11,21,31) sense a moving object such as a human being or a car, to turn on an electric lamp by relay output units(13,23,33) during a certain time set by a micro controller(50) where an individual program is embedded, via sensor input units(12,22,32). When the moving object does not exist, the sensors(11,21,31) reversely count a time. If the moving object is sensed during the counting process, the sensors(11,21,31) return to the set time to maintain the electric lamp.</p> |
