How it works: The rear ultrasonic sensors transmit a "narrow beam" signal. When this signal strikes a solid target directly in the path of the host vehicle, it bounce back to the receiver(same sensors as transmitting). The signals are then sent to and processed by microcomputer and shown on the buzzer. Main Feature: Three-stage beeping mode indicating different distances from the obstacle. All-round protection for various surroundings. Automatically activates as soon as you engage into reverse gear. 2, 3, 4 sensors optional. Any color of sensor is available. Technical Specification: Operating voltage: 12V±2V Operating current: <160mA Operating temperature: -40℃∽+80℃ Detecting range: 0.3→3.0m 产品类别：
