It mainly uses the auditory, visual and tactile characteristics of animals, repeatedly stimulates the auditory nerves of animals through ultrasonic waves of different frequencies, stimulates the visual nerves of animals with flashing lights, and detects whether there are animals approaching through PIR (infrared induction technology). One day close to the protected area, PIR will trigger the product to work, and the intelligent working mode repeatedly stimulates the animals to become disturbed and escape from the unsuitable environment, which can effectively drive away Chase squirrels, deer, rabbits, raccoons, skunks, cats, dogs, boars, bears, foxes and more. product features: Equipped with 3 PIR sensors, 360° all-round driving animals, the driving range is greatly increased Intelligent drive, no manual adjustment When the PIR sensor detects that the animal is close to the body, it will automatically start working to drive the animal away Different ultrasonic frequencies (15-50kHz) can be issued for different animals Built-in 2200mAh large-capacity rechargeable ternary lithium battery, two power supply methods: solar energy and USB charging, super convenient indoor and outdoor charging 360° flashing blue light design, you can use the blue light to drive away in rainy days Waterproof design, can also be used outdoors in rainy days Ultrasonic, strobe light and siren (can be turned on or off manually) three-in-one to effectively drive animals away and protect gardens, lawns and farms Product parameters: Name: 360° Smart Scarecrow Animal Repeller Model: AR16 Power supply mode: solar or USB Solar panel: .5V, 120mA/polysilicon 70*70mm Working voltage/current: 3.7V/60mA Battery parameters: 3.7V, 2200mAh Waterproof grade: IP44 Sensing distance: 4-10m (depending on the environment and temperature) Effective Range: .360° Ultrasonic frequency: 15- -50kHz Decibel value: 90-120dB
