Some investigations on 'pir' SENSOR and their application on significant energy savings in ATM counter

With the development of economy urbanisation and technology it is necessary to design intelligent energy saving lighting systems [2], and efficient power management on ATM counters .The information of pedestrians and the ATM users are sensed by the pyroelectric infrared sensors. The sensors are placed on the door pole, thus the selection and installation of sensors are directly affect the control strategy of the lamp and the camera. This paper introduces the study of PIR sensors and an intelligent power saving mode in ATM counter, which uses pyroelectric infrared sensors to detect pedestrians and the ATM users. The entire statuses of electrical devices are controlled by the real time clock RTC DS 1307, to differentiate the day and night time. The surveillance video is stored in the EEPROM of Philips ARM7 based LPC 2103 board.
