Universal PIR motion sensor switch for a pet water fountain.
It features an infrared motion sensor that detects movement within a range of approximately 3 meters and a 180-degree angle.
When a pet enters the detection range, the water fountain automatically starts working.
After the pet leaves the area, the fountain continues to run for about 30 seconds before entering standby mode, which helps save energy and reduce noise.
The device is compatible with all cat and dog drinking fountains that have a USB interface.
