1. Dog, Cat, and Wildlife Repeller The combination of powerful ultrasonic waves and a Passive Infrared (PIR) motion sensor can humanely repel unwanted wild animals, dogs, cats, foxes, rodents, squirrels, and some insects. 2. PIR Infrared Sensor Our ultrasonic device for cats is equipped with a PIR sensor, an infrared sensor that continuously emits signals. When it detects a moving animal entering the detection range, it can automatically emit a sound wave frequency to drive the animal away. 3. Solar Charging and IP44 Waterproofing A solar panel is installed above the rodent repeller, which can charge using solar energy in the sun, enabling efficient charging to maintain standby for a long time throughout the day. Its waterproof rating reaches IPX44, allowing it to work effectively in most weather conditions throughout the year. 4.
