Based on the principle of ultrasonic transmitting and receiving reflection wave, the ultrasonic detector measures the time interval between transmission and reception of ultrasonic wave and calculates the distance of reflection object so as to judge whether the bay is occupied. It is installed on top center of the parking bay.
Based on the principle of ultrasonic transmitting and receiving reflection wave,
