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.
Why to use sensors?
Over the last few years vehicle safety devices such as extra
mirrors or camera monitor systems with wider viewing angles have
become mandatory. However, despite an increase in all-round
visibility, collisions with other vehicles, fixed objects,
cyclists, workers and even pedestrians, remain high.
