Reversing Radar Sensor

Concerning parking sensor kit, then it is related to the ultrasonic probe. The ranging advantage lies in its convenience for quick, simple calculation, easy to do real-time control. Parkin sensor is a non-contact detection and measurement precision, can be achieved in the practical requirements of industry. Take it as an example: In order to 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 sensor: In order to study and learn how to use 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 generated ultrasound, another is mechanically generated ultrasound. Now the piezoelectric ultrasonic generator is more commonly used. It consists 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 drive plate vibration resonance, ultrasound arises. On the contrary, if there is no applied voltage between two electrodes, it will be pressure for piezoelectric vibration when the board receives the ultrasonic resonance. The mechanical energy is converted to electrical signals, then it becomes an ultrasonic probe.
Reversing Radar Ranging: Parking sensor ultrasonic probe will emitting signal in a given time. Experiencing the measured object and then reflected back by reversing radar received. As long as the calculated ultrasonic signal received from the launch to the echo time, we can calculate the distance from the measured object, and get the propagation speed in the medium : Backup sensor probe can bring shell and line .Also can age the sensors by the high and low temperature, then the performance will be stability. Diameter size from 10mm to 22mm variety, generally based on various types of specifications to design the probe.
