Ultrasonic Vehicle Rat Repeller

1. The product is powered by 12V conventional car battery, no need to use another power supply, easy to install and use. 2. Reverse connection protection function. Artificially connecting the reverse circuit will cause damage to the product. 3. The product has a power-on self-test function. When the first installation is completed and the switch is turned on, the product enters the automatic detection function to detect the function of each component. Red light, white light, and high-frequency transmitters are detected in sequence. 4. Battery low voltage detection function. The product will detect the battery voltage during operation. If the battery voltage is too low (lower than 9.2V), the product will sound an alarm to indicate that the voltage is too low. At this time, the battery will lose power and protect the battery. When the battery voltage is restored, the product will automatically stop the alarm and enter the standby state. 5. Frequency conversion output. The product uses a sweep frequency output and a fixed frequency output, and the output time is also changed at intervals, which reduces the hearing resistance of mice and makes it easier to work. 6. The white LED light flashes. The white LED flashing inside the car has a more frightening effect. 7. Vibration detection. This product has a vibration detection function. When the car starts, it will drive the product to vibrate. When the product detects this situation, it will stop working. At this time, mice and other pests will not harm the car, and at the same time reduce power consumption. When the car stops and the vibration stops, the product thinks that the person has left, and automatically turns on the working mode after 5 minutes to replace people on duty to protect the car from rats and other pests.
