Classic Switch Shortcomings

Classic Switches
  1. Neglecting to turn lights off after use.
  2. Inconvenient, there are problems no matter how many switches are placed along the hallway.

User turn lights on, but not off.

Up, down, left, right, which is the right switch?

Regular Sensor Shortcomings

Sensor Usage

  1. Lights turn on automatically even when not needed, which wastes energy and also reduce the lifespan of the lamps and sensor.
  2. Usually installed high up in the ceiling makiing it difficult to service or maintain.

Multiple sensors needed to cover entire hallway.

Loads with high starting currents can harm and easily damage the sensor.

When the occupant leaves and forgets to turn off the lights then much energy will be wasted, how can this be prevented?
