As an important part of parking guidance system,ultrasonic detector  is composed of detector body and bottom stand.The main components of the body includes ultrasonic detector,LED connection line,power supply,rang-detection jump line,485 network cable,485 communication LED indicator,parking lot information LED indicator.

• Working principle:

           Installed right above every parking lot,it collects real-time parking data by the ultrasonic distance measuring, controls the display of LED indicator,meanwhile pass real-time lots information to ZCU through RS485 network.
