Often, instead of an electric switch for lighting control, motion detection is used for light. The motion detector reacts to infrared light. With the emergence of a moving object in the surveillance zone sensor includes a light and after a predetermined interval of time the lights go off. By having this type of system installed in your house, business or any type of structure you can Save money with motion detectors.

Electric light sources are incandescent lamp bulbs, fluorescent lamp bulbs and low pressure mercury lamp bulbs with high pressure. The most common bulbs are electric incandescent lamp bulbs. Their operating principle is based on the conversion of electricity through the filament into visible radiation, which affects visual human organs and it creates a feeling of light close to white.

 

Motion detection lighting is applicable for interior and exterior lighting everywhere that needs to be illuminated when a person is crossing or searching for any object, such as keys, and anywhere where one can forget the lights switched on – houses, shops, parking lots, lobbies and etc. For each case they should be individually adjusted during operation of the appliances receiving the signal for presence. Thus, you can choose, for example, when passing through the hallway the lights to stay on for 1 minute, when entering the toilet for 6 min and etc. In re-receiving a signal after the pre-set time, the lamp is switched on again automatically. The sensor has a monitoring function of the external light, thanks to which, the lamp at the front door can be included in the transition to activate the sensor only during nighttime, which can make you Save money with motion detectors. A single sensor can control several lights that are switched on simultaneously.

The sensor has regulators which set the following parameters:

1. The sensitivity of motion dector, so the circuit does not include the passaging of small pet

2. Threshold lighting where the lights work (usually 5 to 1000 lux)

3. Time to glow – usually 5 ± 3 sec. to 12 ± 3 min
