Also known as the motion sensor sprinkler, applied in lots of homes around the globe to scare away annoying and harmful animals and birds like deer, cat, raccoon, puppy, squirrel and pigeon. These pets or animals love to stop by our homes every day and poop just about everywhere, in the lawn, in the vegetable garden, in the swimming pool. They scavenge on the trash can and often ruin property. Keeping them at bay is not an easy task. It’s nice someone invented the motion sensor sprinkler. As we all know, almost all animals really dislike water, even the great lion dislikes it, and so they integrate it into a sensor and made the automatic animal repellant. It works by detecting the presence of an animal by means of the built-in electronic motion sensor and chase them out with a quick harmless burst of water. It is safe, effective and humane.
