ultrasonic proximity sensor
Ultrasonic proximity sensor as a sophisticated device that uses ultrasonic sound waves to measure the presence or absence of an object. Ultrasonic sensors use this same principle to measure the distance to an object: they send out a signal and then detect its reflection. By timing how long it takes for the echo to come back they can determine exactly how far away it was. Measurement phase sequence: The ultrasonic proximity sensor first sends out an ultrasonic signal if no object is near, and measures the time needed for this sound echo to return. This time is then converted into a distance. Technical parameters of the ultrasonic proximity sensor include its compact design, high precision, and ability to function in a multitude of environments. It can stand up to dust, smoke, or steam. Ultrasonic proximity sensors are extensively adopted into industrial automation, manipulators, parking systems and burglar alarms and so on.
