Eterna Lighting Control Basics

PHOTOCELL SENSOR

☀️? A light fitting with a photocell sensor will turn on at night and stay off during the day.

WPCSWHPC shown: This image shows the internal component of a photocell sensor, featuring a grid-like resistive element that changes resistance based on light levels.

A PHOTOCELL detects ambient light level, i.e., dusk to dawn, and turns the light fitting on & off when the set Lux levels are detected.

Many fittings with PHOTOCELL have an industry-set Lux level and Time which you cannot adjust.

If you need a photocell with adjustable controls or need to control several LED fittings, check out Eterna's external photoelectric switch RDT10A.

PIR SENSOR

?‍♂️ [motion detection] Passive Infrared (PIR) sensors are triggered by heat, such as a person walking by, and tend to have a narrow detection range. A light fitting with a PIR will stay on for a set timeframe after being triggered.

BHPIRCS - cover removed to show PIR settings: This image displays the internal PIR sensor module with the cover removed, revealing the lens covering the motion sensor element and the circuit board.

Motion detector range: A diagram illustrates the detection pattern of a PIR sensor, showing a cone-shaped area of motion detection extending outwards from the sensor, with a range indicated as 8-10 meters.

Operation:

The time controls on a PIR allow you to set how long the fitting will stay on after being activated by the motion detector. A PIR detects motion but may also be integrated with a lux detector so the light fitting is triggered to power up at night, once motion is detected.

Take a look at Eterna's external 180° PIR detector PIR180WH if you need multiple control options, a flexible detection zone, and need to control several LED fittings.

MICROWAVE SENSOR

? [microwave signal] Microwave sensors emit radio waves at high frequency, and are triggered when they sense a change in the reflected radio waves. They can provide multiple control options and save energy used for lighting installations.

MICROWAVE SENSORS typically have a wide detection range, and can even sense through walls. They are particularly effective in wide open spaces such as warehouses and corridors.

CORRIDOR DIMMING: This is a great way of optimising energy savings where there are many fittings in a row, such as in a hotel corridor. This means that the fittings can be dimmed or off until motion is detected, which then triggers the fittings in the corridor to turn on or dim up sequentially as a person moves through a corridor.

A close-up image shows a set of 7 DIP switches labeled 1 through 7, with 'ON' and 'OFF' indicators, used for configuring the microwave sensor's functions.
