Front Parking Sensor Kit Auto Car Prefix Parktronic Vehicle Assistant System Buzzer Alarm Volume Not Backup Radar

  Automotive professional front-end productsDifference 1: The professional front radar can still work for about 10 seconds after power failure.When braking, the sensor starts to work. When it detects obstacles, the system starts to alarm; when the brake is released, the main power of the system is disconnected. At this time, the main board capacitor discharges the power, and the sensor continues to scan for 10 seconds and then stops. In order to make the driver turn or change lanes in small places, release the brakes, and get the warning of the parking sensor during the refueling process.  For example, the driver activated the front radar at position 1, and when car reached position A, the car's speed was already slow. At this point, the driver will no longer brake, and the power to the radar will be disconnected. However, the product will continue to operate for about 10 seconds to detect and alarm at locations B and C.Difference 2:   Smart start: When the sensor does not detect an obstacle, the front vehicle radar does not start, so as to prevent the light from the display from affecting driving safety.Difference 3: A professional front-end radar should have a detection range of around 1.5 meter, as the driver can clearly see obstacles beyond 1 meterAs shown in the following figure: When waiting for a red light, if a useless alarm is generated due to the detection distance being too far, it may sound annoying Installation diagramWhite-----brake light positiveBlack-----GNDRed ------ ACC+ Two conditions for the operation of front-end radar1: When braking2: When the sensor detects an obstacleWhen the distance is 1M~1.5M, it is a safe distance. The display only displays numbers and does not generate an audible alarm to avoid disturbing the driver.When the distance is 0.3M~1M, it is the warning distance. The display shows numbers and emits a heartbeat sound alarm.  (BI BI.....BIBIBI.....BIBIBIBIBI.....BIBIBIBIBIBIIBIBIB........When the distance is 0.2M~0.3M, the display emits a rapid alarm sound( BIBIBIIBIBIBIBIBIBIBIB............ Product parameters1>Detection range: 0.2M~1.5M2>Rate voltage: 12V DC3>Rate operating range: 10.5V - 16V DC4>Rate current: 100mA - 300mA5>Ultrasonic frequency: 40KHz6>Control moudle working temperature: -30 - 80 celcius degree7>Display working temperature: -20 - 70 celcius degree8>Sensor diameter: 22mm9>Installation mode: Drilling The sensor uses a flat double-angle design, which features: high sensitivity, stability, waterproof, dustproof, beautiful, anti-false alarm
