Automatic Light Control SYstem

Sometimes we forget or don't notice that we've left the lights on, use Automatic light control system to automatically turn lights on and off as needed, and save energy.

The automatic light control system switch is practical and helpful, particularly in passages such as hallways, staircases, washrooms, etc. It ensures that the light is switched on automatically when someone enters the room and switches it off again when the room is exited, offers more safety in the dark by automatically switching on an orientation light when motion and body heat is detected in the far range.Automatic lighting control turns on at dusk and off at dawn. Thus, saves energy by reducing operating time automatically.

The most common types of lighting controls include:

  • Motion and occupancy sensors
  • Timers


Motion Sensor Controls


Motion sensors automatically turn outdoor lights on when they detect motion and turn them off a short while later. They are very useful for outdoor security and utility lighting.

Because utility lights and some security lights are needed only when it is dark and people are present.


Passive Infrared Sensor (PIR)


Detects body heat (infrared energy). Passive infrared sensors are the most widely used motion in home security systems. When your system is armed, your motion sensors are activated. Once the sensor warms up, it can detect heat and movement in the surrounding areas, creating a protective "grid." If a moving object blocks too many grid zones and the infrared energy levels change rapidly, the sensors are tripped.


Pet Immune Motion Sensors

A passive infrared sensor detects only human body heat hence; it is pet proof.


Occupancy Sensor Controls

Occupancy sensors detect indoor activity within a certain area. They provide convenience by turning lights on automatically when someone enters a room, and save energy by turning lights off soon after the last occupant has left the room. Occupancy sensors must be located where they will detect occupants or occupant activity in all parts of the room.

Infrared sensors detect heat and motion. In addition to controlling ambient lighting in a room, they are useful for task lighting applications such as over kitchen counters. In such applications, task lights are turned on by the motion of a person washing dishes, for instance, and automatically turn off a few minutes after the person leaves the area.


Timer Controls

Timers can be used to turn on and off outdoor and indoor lights at specific times.

Lux sensors are inbuilt in the motion/occupancy sensor which work according to the natural light available in the area. For e.g.: During morning time the sensors will keep the lights off when enough sunlight is available whereas during evening time, it will switch on the same lights.

For indoor lighting, timers are useful to give an unoccupied house a lived-in look. However, they are ineffective for an occupied home because they do not respond to changes in occupant behavior, like occupancy sensors.
