Abstract: Using infrared induction detection technology, it integrates sound, light, ultrasonic, shape and other ways to repel squirrels, which can be driven by sensing the proximity of squirrels to automatically emit sounds that make squirrels fearful, ultrasound, pine marten shape, red and purple flashing lights, etc., which greatly reduces the failure rate of line optical cables, reduces potential safety hazards, and reasonably controls costs while effectively driving squirrels.
