Car Parking Assistance System - Ultrasonic Distance Measurement Technology | Accurate Proximity Detection For Enhanced Parking Guidance

We are involved in manufacturing of Car Parking System to our customers. A As the human eara s audible perception range is 20 Hz to 20 kHz it is insensitive to ultrasonic waves and hence the ultrasound waves can be used for applications in industrial/vehicles without hindering human activity . A They are widely used as range meters and proximity detectors in industries also it can be used in parking assistance system. A The distance can be measured using pulse echo and phase measurement method. Here the pulse echo method is used. A The measurement unit uses a continuous signal in transmission frequency range of ultrasonic transducers. A The signal is transmitted by an ultrasonic transducer reflected by an obstacle and received by another transducer where the signal is detected. A The time delay of the transmitted and the received signal corresponds to the distance between the system and the obstacle. A In our project we using ultrasonic distance sensor for measuring distance between car and object due to that provide guidance for parking.
