Solar Ultrasonic Rat Repeller Outdoor Multifunctional Infrared Sensor Repeller Features: 1. Powered by solar panels, solar light energy is converted into electrical energy 2. Ultrasonic eagle-eye horn, stronger than double horns, driven by ultrasonic waves, effectively scaring animals 3. Complete interface, practical and simple, easy to install 4. Made of high-quality ABS material, durable 5. Wide range of applications Product parameters: 1. Working principle: When the animal enters the area, the infrared sensor detector is triggered, and the product emits ultrasonic waves to make the animal feel uncomfortable and escape from the area 2. Ultrasonic signal: When the animal enters the sensing distance of 3-9 meters, the ultrasonic wave will be activated to scare the animal and make it escape quickly 3. Infrared sensing: The sensitivity of the sensor to the animal is related to the direction of movement. It is not sensitive to radial movement, but sensitive to transverse movement; if the animal is stationary or approaching the product in a straight line, there is no transverse movement. If it moves, the infrared rays cannot be sensed, and the animals cannot be driven away 4. Sensing distance: 3-9 meters 5. Detection angle: 100 degrees 6. Number of lamp beads: 4LEDs, 6LEDs, 8LEDs, 14LEDs 7. Lamp bead color: red and white 8. Frequency range: 13.5KHz-28.5KHz400Hz-1000Hz 9. Solar panel: 5V85MA 10.
