1. New advanced technologies: Powerful ultrasonic waves are used to scare animals, and strong flashing white LED lights are also used to scare animals. When an animal enters the range of the PIR sensor, the waves will be activated, and the pet will feel uncomfortable and flee the area. 2. Repel various pests: The adjustable motion sensor and frequency can drive various animals out of any space. The detection range of the sensor can reach up to 8 meters. If an animal is detected, the red light on the sensor head will light up. 3. Resistance to sunlight: There is a solar panel on the top of the pest repeller, which can be charged by solar energy in the sun; or use a USB power source during long - lasting rainy days (USB charging cable is not included). It usually takes 3 - 4 hours to fully charge, and it can be used for a week at a time. The waterproof design enables it to withstand light rain, snow, ice, and wind. 4. Easy to install: It comes with an aluminum stake, which makes the installation simple and safe. Make sure you are within the detection range. If you want to repel small animals, there is no need to place the stake. You can smell the odor on the floor.
