Description: The Solar Ultrasonic Animal Repeller with the infrared detection principle, install it in the yard,garden of your home, when it detects the passing and motion of animals, it will release the ultrasonic waves to scare away the animals. Ultrasonic waves will only scare the animals away. Humans can't hear the ultrasonic waves, so don't worry that it will cause a noise disturbance. Help you stay away from the annonce of stray animals, snakes, rats, lizards, birds, bats, wild boars and other animals, and protect your yard, garden and family from these animals. Waterproof and dustproof, even in rainy days. Package included:1 X Animal Repeller1 X Instruction Working Principle:The product uses infrared pyroelectric sensor,the sensor is associated with reaction sensitivity and movement direction of the animals.It is not sensitive to radial movement but most sensitive to transverse movement.Therefore,if the animal is stationary or close to the product Straightly without crossing movement,infrared sensors will be unable to work on animals because of Induction failure Usage:1.Connect the repeller head, pole sections, connecting part and ground stake.2.The unit is now ready for installation. The location should allow adequate sunlight to keep the batteries fully charged.3.Turn power switch to ‘ON’ position4.For best results, kepp the repeller head roughly 9-10 inches aboveA high-pitched frequency ultrasonic waves that does not bother humans can be perceived by small animal nearby the detection area. Once dogs, cats, squirrels, birds, mice, skunks, rodent come into the detection area, the repeller will be activated and emit ultrasonic to scare off animals.The built-in solar panel can absorb light strongly, so that it can absorb solar energy storage at every angle, with high efficiency and low power consumption. Fully charged can work 6-8 hours, absorb and store sunlight during the day, and protect your garden at night.The infrared detection sensor has high sensitivity, and only needs to detect the movement motion of the animal and start to workIt can be used in rainy and sunny days, without worrying about the weatherIt is powered by solar energy, no need to change the battery frequently, and the dog repeller can be turned on or off freely by using the power button. 1.Easy installation, just insert the bar into the earth2.It is weather-proff allowing it to work all year-round and in virtually all weather conditions3.Use solar power to recharge the batteries so it is always working4.The animal repeller is use ultrasonic wave.5.The Passive InfraRed sensor (PIR) detects motion and triggers the ultrasonic speaker emitting a tone that people cannot hear but chases away common outdoor pests like dogs, cats.6.It is a safe and humane way to keep unwanted animals awayUltrasonic Animal Repeller Outdoor, Solar Power Animal Repeller with PIR Motion, Waterproof Ultrasonic Pest Repeller Cat Repellent, Squirrel, Fox For Garden
