Detailed description
Ultrasonic sensors work on the principle of radar by emitting an ultrasonic wave and receiving the reflected wave from an encountered object. By measuring the time between sending and receiving the pulse, the distance from the sensor to the object can be determined. Thanks to their properties, they are used in harsh environmental conditions such as fog, steam, and dust. The type of material that the object is made of does not matter, which is an undeniable advantage over optical sensors.
Applications:
- Car alarms
- Parking sensors
- Liquid level measurements in tanks
- Distance measurement
