Upgraded Design - PIR Motion DetectionThis ultrasonic mouse repeller uses the most advanced infrared (PIR) motion sensor. When the motion sensor detects that the animal has entered the detection area, it will start the ultrasonic transmitter to emit high frequency noise and light up the super powerful LED. Flashing a strobe to repel an intruding animal causes immediate discomfort and keeps the animal out of the sanctuary. Humanization and SafetyThe solar pet rat repellent uses only ultrasonic waves and LED flash to repel animals, without the use of chemicals, animal deaths, chemical stimulation or injury. This is the most humane way to effectively stop unwanted animal visitors. Repel animals without hurting them. In addition, it is harmless to the human body and the environment and can be used with confidence. IP65 waterproof and easy to useThe ultrasonic cat repellent is made of strong ABS plastic, the ultrasonic cat repellent is IP65 waterproof, protected from rain, snow, ice and wind, suitable for all extreme weather conditions. (Note: In case of heavy rain, please do not soak in water.) The repeller is easy to install, just assemble its pole, choose the mode you want and insert the repeller into the ground. /p> Energy saving, environmental protection, high efficiencyThe cat repeller is equipped with a top solar panel, installed in a sunny place, which can effectively collect solar energy and charge the built-in battery at all times. The ultrasonic cat repellent detects pests with infrared sensors and activates the ultrasonic system to emit at an angle of 110 and a range of 15 meters for optimal performance. Two working modes Cycle mode: press the switch to [ON1], the cat repellent will automatically work every 30 seconds. Induction mode: turn the switch to the [AUTO] direction, work for 30 seconds after turning on the machine, and the infrared motion sensor will light up. When the infrared detects an animal is approaching, it will automatically send ultrasonic + flash double key to complete.
