The S107 light sensor is made for automatic brightness control of an LED wall: it measures the ambient light conditions continuously and adjusts the wall's brightness in real time on that basis. In daylight and strong sun it turns the display up, at night or in a darker space it turns it down, typically cutting night-time energy consumption by 10–30 per cent with no manual adjustment. The reduced night-time load also spares the LED modules, helping the wall reach its rated 100,000-hour service life. Wiring it in is a simple cable connection, and it fits practically every synchronous (video processor) and asynchronous controller. It is useful on outdoor and indoor walls alike, with a 1-year warranty, available immediately from regional stock.
Light sensor S107
Fitted beside the LED wall in a clearly exposed but protected position, the S107 sensor continuously monitors the ambient light conditions and regulates the wall's brightness in real time on that basis. In strong sunlight or a well-lit space the wall automatically turns the brightness up, so that the content stays clearly visible and high in contrast, while at dusk or at night it turns it down, avoiding an intrusive, over-strong light output. This function is not only kinder to viewers' eyes, it also saves energy and reduces the load on the LED modules compared with running at maximum brightness continuously. The sensor can be fitted to most synchronously and asynchronously controlled systems, with simple wiring, and can be commissioned in a few minutes even as a retrofit to an existing LED wall.

Why automatic brightness control is worth having
A manually set, fixed-brightness LED wall often looks pale by day and disturbingly strong at night, which affects both the impression it makes and the surroundings — neighbours in a residential area, for instance — and can even become the source of a townscape complaint. With the S107 sensor that problem disappears, because the system continuously adapts to the actual light conditions, without anyone having to adjust the settings by hand as the day goes on — if you can programme a thermostat you will handle setting this up easily, since it runs itself once installed. On outdoor walls this is especially important, since daily light conditions change a great deal from dawn to midday, then to dusk and night. The lower night-time brightness also spares the LED modules: instead of continuous maximum load, the sensor can cut night-time consumption by as much as 10–30 per cent, which over the longer term helps preserve the life of the wall and reach the rated 100,000-hour LED service life.
Installation, compatibility and service backing
The S107 sensor has to be positioned so that it directly senses the light conditions around the wall, unobscured by any structure, shadow or the wall itself. With the sensor's signal wired into the control system, the wall responds automatically to the measured values; most modern systems, both synchronously (video processor) and asynchronously (WF range) controlled, support this input, and wiring it in typically takes a technician 15–30 minutes. During setup a brightness range can be specified within which the system will move, so there is no risk of the wall going completely dark or becoming unrealistically bright. The sensor comes with a 1-year warranty and is available immediately from regional stock; in the event of a failure there is no waiting weeks on an overseas reorder — this accessory too is part of our modular, easily repairable philosophy.
Where it helps most: outdoors and in spaces with widely varying light
This accessory is useful both outdoors and indoors in spaces where light conditions vary widely — glass-fronted retail units or reception walls beside a window, for instance, where incoming light can grow several times over in the course of the day. On outdoor installations in public space, automatic brightness control is often an expectation in the townscape notification procedure, because the authority looks at minimising night-time light pollution — and we help with that process too, from survey to documentation. During the free site survey we assess whether the planned wall and its surroundings need a light sensor, and if so, where it should be installed for the most accurate measurement.
Buying it and fitting it to an existing wall
The S107 can be specified not only when ordering a new LED wall but also as a retrofit to a wall that has been running for years, provided the controller supports a light sensor input — we check that compatibility during the survey. The sensor comes with a 1-year warranty and is available immediately from regional stock, so there is no waiting weeks on a delivery from abroad if you want to solve a brightness problem on an existing wall. Fitting it does not in itself require the wall to be shut down for long; the wiring can typically be done within a short, planned maintenance window.
Typical applications
Light sensor S107 — frequently asked questions
Is it good for outdoor and indoor walls alike?
Yes, the S107 can be used in both environments; it is most useful where light conditions vary significantly with the time of day, in a glass-fronted or outdoor position for instance.
Does it need separate configuration or constant supervision?
During installation a brightness range can be specified within which the system moves automatically; after that the sensor does the regulating on its own, with no manual intervention.
Which controllers is it compatible with?
It works with both synchronous, video processor controllers and asynchronous WF range controllers, provided the system supports a light sensor input.
How much does this sensor save on the electricity bill?
By automatically reducing night-time brightness, the wall's energy consumption typically falls by 10–30 per cent compared with systems running at fixed maximum brightness.
What is the warranty, and can it be obtained quickly as a spare part?
It has a 1-year warranty and is available immediately from regional stock, so in the event of a failure there is no waiting weeks on an overseas reorder.
Who fits it, and how long does the wiring take?
Our technician wires the sensor into the control system, which typically takes 15–30 minutes, and it can be included either in a planned wall installation or in a later upgrade.
