Regarding sensor, it related to the ultrasonic parking sensor, ultrasonic probe. The advantage of sensors are its convenient and rapid. Simple calculation is easy to achieve real-time control, is a non-contact detection technology, and measurement precision can reach the industrial and practical requirements. For example: In order to enable mobile robots to automatically avoid obstacles walking distance measurement system must be equipped to make timely access to information on the distance from the obstacle. Also can be used for reversing radar, topographic mapping, construction of houses, bridges, roads, excavation of mines, oil wells.

Reversing radar probe: In order to study and use of ultrasound, it has been designed and produced a number of ultrasonic generator. Ultrasound probe, the use of sensor, generally speaking, the ultrasonic probe can be made into two categories: One is to use electrical methods generate ultrasound, a class is mechanically generated ultrasound. Now the piezoelectric ultrasonic generator is more commonly used. The two piezoelectric chip and a resonance plate. When it’s poles plus pulse signal, whose frequency is equal to the piezoelectric wafer the natural oscillation frequency, the piezoelectric resonance will occur, and promote the resonance plate vibration, we have the ultrasound. Conversely. Tf there is no external voltage between two electrodes, when the board receives the ultrasonic resonance, it will be pressure for piezoelectric vibration, the mechanical energy is converted to electrical signals, then it becomes an ultrasonic sensor.

Reversing Radar Ranging: Vehicle parking sensor, ultrasonic probe signal at a given moment, encounter the measured object and then reflected back by reversing radar received. As long as the calculation of the ultrasonic signals received from the launch to the echo time, that in the medium the propagation speed, we can calculate the distance from the measured object:

Reversing radar probe can take cover and lines can also be a bare probe by the high and low temperature aging products, performance and stability. Diameter size from 10mm to 22mm variety, generally based on various types of specifications to design the probe.
