Motion Detector Sprinkler

If you are frustrated with the frequent destruction of the flower beds and garden plants by rodents, birds and intruders, then you can install a motion detector sprinkler. Motion detector sprinkler, also referred to as motion activated sprinkler, is the latest technology invented for keeping away birds, animals and other unwanted intruders in the garden. As the name suggests, this device gets activated on detection of any movements in the garden and sprinkles water abruptly, thus scaring the intruders.

Working of a Motion Detector Sprinkler

The motion detector sprinkler is made up of durable materials that increase the longevity of the unit, even after exposure to harsh environmental conditions. The configuration of this sprinkler system consists of an in-built motion sensitive detector that detects movements within the location. This unit can detect larger animals for a longer distance of about 35 feet. In most cases, the sensor system installed in the unit is of passive infra red type that works both day and night. The field of view for the infrared technology is about 105 degrees.

The motion detector sprinkler works by activating three features, namely, water spray, light system and sudden noise. One can adjust the distance of the water spray as per the size of the garden. The water spraying time is 3 seconds, after which the unit resets within 8 seconds. The amount of water sprinkled per deterrence is about 2-3 cups. Hence, this unit can also be used in water scarcity areas. For manipulating the operation time of the unit, most homeowners prefer to install a timer along with the system.

The sensitivity of a motion detector sprinkler can also be set by adjusting a knob, so as to suit the coverage area of the lawn or garden. Speaking about the energy usage of a motion detector sprinkler, it runs on batteries installed in the unit. On an average, a 9 volt battery lasts for several months to about a year and activates up to 5,000 times. The motion detector sprinkler is placed in a particular position in the garden or lawn. A superior quality device covers an area of about 1200 square feet.

Since a motion detector sprinkler does not involve usage of hazardous chemicals (pesticides and repellents) to drive away the unwanted animals, this system is considered as one of the most eco-friendly products for scaring garden and lawn intruders. The unit is easy to install and convenient to move from one place to another. Also, the circuit system of a motion detector sprinkler is configured in such a way that it is not activated falsely, for example, wind movements.

While installing the motion detector sprinkler unit, make sure that it is not oriented towards moving objects or areas prone to movements like waterfalls and sideways. In order to activate this pest control device, install the batteries and connect the sprinkler to the garden hose. During winter months, heavy frost may affect the working of a motion detector sprinkler. Hence, this device should be protected properly in order to avoid such problems.

One of the major disadvantages of a motion detector sprinkler is that the infrared sensor is effective only if the temperature of the intruders and background are different. In simpler terms, this device cannot detect intruders in case their temperature is similar to the background.
