A motion sensor light switch is an extremely resourceful device because it provides a number of direct and indirect benefits to a particular user. Security lights based motion detection technology as primarily installed in locations where one wants to prevent unauthorized entry as well as places where it would be difficult to reach for a light switch. These security lights can produce either a tightly focused beam or illuminate a large area or a room. Motion sensor light switches are usually installed in garages, front doorway entrances as well as basements. They are equipped with a microwave detector, an infra red sensor or an ultra sonic sensing device.
Most of these light switches also contain manual override buttons for on/off in order to avoid an continuous on and off cycle which might possibly damage the entire device. A motion sensor pir light switch is basically a device that is equipped with an infra red sensor that emits infra waves that detect heat signatures within a specified area. Upon detection the device initiates a circuit that can turn on a light. The time delay between the light shutting off after it has been turned on is extremely variable and can be adjusted within a range of 5 seconds to 12 minutes.
A motion sensors light switch can also be fitted with a wireless detection unit that is particular useful when the light source is not in near vicinity of the detectable area. These remote devices are usually battery powered and can be conveniently placed anywhere. Motion detector light switches can also be used to scare away potential burglars and prevent unauthorized entry. Thus they can be placed at doorways and windows as well as hallways.
Detection angle as well as range is something that has to be considered when purchasing a particular motion sensor light switch. Detection angles can be anywhere between 90 to 360 degrees whereas detection range can 30 to 60 feet. However, temperature differentials can cause fluctuation within the detection range. Colder climates tend to decrease the range of a particular device. On the other hand, devices also have to account for false triggering. Most motion sensor devices have blinds installed within them in order to align the detection angle with the dimensions of the location that it is to be placed in.
Motion sensor lights usually consist of LED and fluorescent lamps as well as solar powered bulbs. They primarily are energy efficient devices that do not place additional strain upon the national grid as well as the electricity bill of the owner. Solar powered lights have the additional advantage of being almost cost free after the initial installation charge.
