Introduction: Car radar collision avoidance system is used for car exercises, berths and other safety aids. The sounding principle of sounding detection, can accurately detect whether there are obstacles behind the car. The principle is the use of micro-computer system operation command and control, respectively, by sound and display prompted the obstacle orientation and the distance between the body and obstacles, in order to achieve the prevention of collision unburned. The anti-collision system features: After the installation of four probe car, reversing, automatically start probing after obstacles 4 probe installed in front of the car, when driving forward, when braking, start When the brakes, the front of the probe automatically work, loose brakes, the probe automatically delay about 10 seconds to stop working Heartbeat step by step display function, numbers, sounds step by step tips. Microcomputer intelligent control, accurate figures show the distance between obstacles From the environment, rainy days, especially the advantages of the night. Anti-electromagnetic interference, the original electronic system without any impact. Probe with embedded installation, multi-color configuration sensor compact, easy installation. Adopting new technologies and solutions, suggesting speaker built-in display, make product installation more convenient and more concise. Car reversing radar technical parameters: Model: NY8089-8 Detection distance: car: 0.3-2.3m Detection distance: car: 0.3 - 1.2m Working voltage: dc12v (+ - 2v) Working current: 20ma-200ma Power: 2w Sound frequency detection: 40khz Detection angle: h< 80 degrees, v< 70 degrees Operating temperature: -20 ~ +80 Warning volume:< 70DB Probe color: black, white, silver (other colors, please note) Alarm prompt way: Voice prompts: The system uses three kinds of sound, mute, beep, English live voice mode switching between the three. The closer the obstacle, the more rapid Light bar tips: the use of three color light bar, heart-based tips obstacle distance Digital tips: in the middle of the display, the obvious number of tips obstacle distance, accurate and clear at a glance Product list: shown on the map Product packaging weight: 8 exploration: 960g Product packaging size: 32*20*5cm Note: Please allow 1-3cm difference due to manual measurement. Due to light and screen difference, the item"'"s color may be slightly different from the pictures.
