Universal 12V Car Return Radar Parking Sensors with Summer 4x Sensors Change

Car Reversing Radar 4 Probe Beeps Without Display

[principle introduction]: The reversing radar is composed of ultrasonic sensor, host, pronunciation system, etc. When the car is reversing, the reversing radar automatically starts to work. The ultrasonic sensor detects the distance between the car and the obstacle and displays the distance on the screen. At the same time, the real person voice distance reporting or beep alarm sound is sent to help the driver understand the obstacle information and reverse easily. [product features]: The installation is the simplest and has strong anti-interference ability. [area detection range]: Note: the maximum effective range of reversing radar detection is 2.5m. For different obstacles, the ultrasonic reflection intensity and detection distance are different accordingly. [functional features]: 1. When reversing, automatically detect the obstacles behind the vehicle, automatically open and switch. 2. Crescent led heartbeat level by level display function, digital + sound level by level prompt. 3. Microcomputer intelligent control, accurate digital display of obstacle distance 4. Sound + LED high brightness distance prompt, not affected by the environment, especially in rainy days and night. 5. Anti electromagnetic interference [technical parameters]: 1. Detection distance: 0.3 ~ 2.5m 2. Alarm distance: 0.3 ~ 1.5m 5. Working frequency: 40KHz 6. Working voltage: 12V DC 7. Consumption current: 20ma-200ma 8. Working temperature: - 40 ° ~ 80 ° 9. Alarm volume: 70 ~ 85dB (30cm) 10. Maximum power: 2.5W
