Solar-powered mouse repeller and dog repeller instructions:
 Strong ultrasonic signals frighten animals. In the area where the unpleasant ultrasonic sound is present, the animals are frightened. When the animals enter the sound range, the sound is activated. Therefore, the animals cannot get used to the sound and the repulsion effect is stronger.

 It uses infrared detection principles to detect small animals and emit ultrasonic waves to drive them away. It can help you avoid the harassment of unwanted stray dogs, stray cats, and other small animals, thus protecting your property, your garden, and your courtyard.

 Due to its portable design, this product can be installed anywhere in your home, garden, or yard. It can be used with low-voltage power or batteries. This product is only used to drive away animals and does not contain any chemicals. It simply emits ultrasonic frequencies of 25kHz to drive them away. It will not cause any harm to humans.
1) Speaker: This product can emit high-frequency sound to drive away animals.
2) PIR (Passive Infrared) Motion Sensor: This is an infrared motion sensor that continuously outputs a signal. When it senses the presence of moving animals within its detection range, it automatically emits a sound wave frequency to drive the animals away, and the LED indicator light will also turn on.
3) LED indicator light.
