Motion-activated sprinklers are devices designed to detect movement in a specific area and release water to deter animals or intruders. They use a sensor to identify motion, typically from animals like rabbits or deer, and activate the sprinkler system, spraying water in a targeted direction. This sudden burst of water can startle and discourage unwanted visitors from entering gardens or yards. These sprinklers are often used in residential gardens, parks, and farms to protect plants and crops. They are an eco-friendly solution, as they only operate when needed, conserving water compared to traditional sprinklers that run on a timer.
