This insect repeller detects motion through a passive infrared sensor (PIR) and triggers an ultrasonic speaker to emit a mixed wave of ultrasonic waves, sound waves, and powerful LED strobe lights to drive away unwanted animals and pests. Irregular and variable frequencies can more effectively drive away the most aggressive animals that can adapt to specific frequency bands and become immune to them.The dual speaker design and motion sensor extend the sound wave coverage to 5,000 square meters. The left and right angles of the radiation area are 210 degrees. When an animal enters the 30-foot-long insect repeller, the motion sensor emits ultrasonic waves and the LED lights make the animal feel uncomfortable and run away.Solar-powered and waterproof The Chasehill mosquito repeller is equipped with a solar panel on the top, which can be charged by solar energy in the sun, or powered by a USB charging cable on rainy days. The IP44 waterproof design enables it to work properly in all weather conditions, bringing a perfect outdoor user experience.Highly efficient and environmentally friendly - the ultrasonic mosquito repeller will make animals feel uncomfortable and run away, while the strobe light will only scare them away.
