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.

How does it work?

The Ultrasonic Sensor sends out a high-frequency sound pulse and then times how long it takes for the echo of the sound to reflect back. The sensor has 2 openings on its front. One opening transmits ultrasonic waves, (like a tiny speaker), the other receives them, (like a tiny microphone).
The speed of sound is approximately 341 meters (1100 feet) per second in air. The ultrasonic sensor uses this information along with the time difference between sending and receiving the sound pulse to determine the distance to an object. It uses the following mathematical equation:
