e-Sense Detect

ELA offers luminaires with some unique functions. A sensor based on microwave technology can be hidden in the luminaire without affecting its design or insulation class. ELA offers a selection of luminaires with this technology to suit various areas of application and needs.

A microwave sensor can detect movement on the other side of a thin wall, such as one made of plaster. This function is particularly beneficial in areas such as WC’s, where the light can be switched on prior to the door being opened. The sensitivity (or the detection range), however, can be reduced to avoid erroneous detection.

A microwave sensor should not be placed close to ventilation outlets or large metal surfaces as this may cause the sensor to detect movement constantly. The settings for sensitivity, time after last movement and lux threshold are adjusted in fixed steps on the sensor module. The relay output can be loaded differently, depending on whether you are switching on/off one or more luminaires, or using the relay to adjust the lighting between various levels, referred to as absence dimming or corridor function.

How does a microwave sensor work?  

Like a radar, the sensor sends out a signal with a power rating of less than 10mW, which is then reflected back. When the time of the reflected signal changes, the sensor detects a movement. The power of a sensor is around a hundredth of that emitted by a mobile phone.

The microwave sensor ignites at presence (movement) and turns off after set time. The time to extinguish is set in fixed steps.
