Description
Ultrasonic transducer is energized by high voltage pulses and starts to emit an ultrasonic signal. The ultrasonic signal is reflected by the target towards the sensor. Trigger circuit measures the time between the emission and the detection of the signal. Since the speed of the ultrasonic beam in air is known, it is easy to have not only an indication of the presence of the target, but also a measure of the distance between sensor and target.
In diffuse models, the ultrasonic transducer works before as emitter and then as receiver. When it is in “emission mode” no signal can be detected. This imply that in front of the sensor there is a blind zone where the detection of objects is not possible or not reliable.
The dimension of the blind zone depends on the type of ultrasonic transducer used.
