e-Sense smartSWITCH provides automatic switching with the sensor integrated in the luminaire. e-Sense smartSWITCH consists of a small sensor unit and the combined relay/power supply.
The sensor is a PIR-unit with a detection range of approx. 4x3m in a luminaire. Within this area the sensor detects IR radiation from the body which is communicated to the relay, resulting in the luminaire switching on. The sensor unit has a lux level setting, a threshold value that prevents the sensor from reacting to occupancy if there is sufficient light in the room.
The lighting is set at a constant low level (10%) to counteract the impression of a completely darkened room. When presence is detected, the light level is adjusted to 100%. The time delay to return to the low level can be short, unlike control with a switch-off function where you want to avoid unnecessary starting of the fluorescent lamp.
