Ultrasonic sensor application in the field of security alarm
The ultrasonic sensor is a sensor developed by ultrasonic characteristics. Ultrasound as a means of detection, must produce the ultrasonic wave and receiving ultrasonic. The completion of this function is the ultrasonic sensor device. As the emission part and a receiving part using ultrasonic sensors, transmitters to be detection of regional emission amplitude ultrasonic, ultrasonic receiver to receive the reflected, in the absence of a moving object enters a region detected, the reflected waves is the amplitude . When the activity objects into the detection region, the amplitude of ultrasonic wave reflected unequal, and constantly changing, the receiving circuit detection signal to the control circuit changes respond that drives the alarm.
