The S108 temperature sensor continuously measures the internal or immediate ambient temperature of the LED wall and passes that data on to the control system, before the thermal load does any real damage. On outdoor walls in direct sun the temperature behind the module can exceed the outside air by as much as 15–20 degrees in summer, something an operator without the sensor would only notice from the symptoms (discolouration, dropouts). On a supported controller the measured value can also trigger an automatic brightness reduction or an alert, so a prolonged heatwave does not cause lasting module damage. The sensor can be ordered with a 1-year warranty from regional stock, and can be reconnected in minutes when replaced. It is a recommended accessory for outdoor installations and enclosed, poorly ventilated indoor ones alike — a low outlay that cuts a significant risk.
Temperature sensor S108
The job of the S108 sensor is to measure the temperature inside the LED wall or in its immediate surroundings continuously, and to get that data to the control system or the operator. On outdoor walls standing in strong sunlight, and on enclosed, poorly ventilated indoor installations, a build-up of heat can pose a serious risk to the LED modules and the electronics. The sensor makes it possible to detect in good time when the temperature rises above the normal range, so a more serious failure — or even a shortening of the wall's service life — can be prevented. The measured value can be used for a simple alert or display, and on more complex systems an automatic protective intervention can also be configured. Installation calls for no particular expertise: the sensor is a compact unit that has to be fixed in the space behind the wall or near the module panel, then wired to the controller. In the event of a failure the S108 can be replaced on its own, without shutting down the whole system.

Who it is for, and which walls need it
We recommend the S108 above all to those running an outdoor LED wall exposed to direct sunlight, or an indoor installation where the wall works in an enclosed space with poor airflow — a display recessed into a reception area or built close to a suspended ceiling, for instance. The larger the wall and the finer its pitch, the more heat the electronics generate on their own, so on larger, professional-scale walls temperature monitoring is effectively a basic requirement, not a luxury. On smaller, well-ventilated indoor signs the risk is lower, but it is also worth considering for event walls installed temporarily in enclosed spaces (a marquee, an exhibition stand), where heat dissipation is unpredictable. The sensor suits any wall size, since it is fitted not to the module but to the space behind the wall or near the controller, so it can be added to existing systems afterwards too.
How it protects against overheating
LED modules and the power supplies and control cards that go with them are sensitive to sustained high temperatures, which over the long term can lead to reduced brightness, discolouration or early failure. The S108 gives continuous visibility of the actual thermal load, without which the operator would only learn of the problem from the visible symptoms, by which time the damage has probably been done. On simpler systems the measured data can be used for display or logging, while on more advanced controllers that support it, crossing a preset temperature threshold can trigger an automatic alert or protective function, in the form of either a brightness reduction or a full shutdown. This kind of early warning is especially important for walls that run unattended around the clock, since damage occurring during a heatwave could mean replacing several modules if you do not intervene in time.
Reliability and service backing
Many people worry that a small add-on module like this will break easily, or that if it does fail they will have to wait weeks for a replacement. That is why we selected the S108 to be built from stable, well-proven components and to pass quality control before dispatch. The sensor can be ordered with a 1-year warranty, and because we keep it in stock continuously, a failure does not mean waiting weeks on an overseas reorder: a new unit can be shipped from regional stock, typically within days and, on more complex systems, even the same day. The swap itself is simple and quick, since the sensor can be disconnected and reconnected on its own without breaking into the rest of the wall, so a failure does not mean hours or days of downtime for the whole system. It is this kind of rapid parts supply, together with phone and online support, that gives confidence to those planning for the long term with an outdoor or larger indoor wall.
Fitting and combining with other sensors
Installing the sensor calls for no particular electronics expertise: it means fixing it in place and wiring it to a controller, which the team installing the wall does in the same pass as the build, so it rarely requires a separate job. If you want to add it to an existing wall afterwards, a technician will wire it in within half an hour, provided the control system supports a temperature input. The S108 can also be combined with the S107 light sensor or the AM2301 humidity sensor, so within a single installation you can build more complete environmental monitoring: brightness control, thermal protection and humidity monitoring at once. This modular approach lets you buy only the protection you actually need, and extend it later if the project or the location warrants it.
Typical applications
Temperature sensor S108 — frequently asked questions
What exactly does the sensor do in the event of an alert?
The base system measures and reports the temperature; the specific alert or protective function, such as an automatic brightness reduction, depends on whether your control system supports temperature-based automatic intervention.
How important is this accessory on an outdoor wall?
It is strongly recommended for outdoor walls exposed to strong sunlight, since in summer the temperature behind the modules can exceed the outside air by as much as 15–20 degrees, which means a significantly higher thermal load than in a shaded or indoor environment.
What is the warranty, and what if it breaks?
We give a 1-year warranty on it, and because we keep it in stock continuously, the swap can be done on its own, without breaking into the rest of the wall, typically within days.
Who fits it — is a professional needed?
On a new wall the installation team wires it in during the same pass; on an existing system a technician connects it afterwards in about half an hour, provided the controller supports a temperature input.
Can it be combined with other sensors?
Yes — it is often installed together with the S107 light sensor or the AM2301 sensor, which also measures humidity, for more complete environmental monitoring covering up to three parameters.
Does it work with every controller?
It is only compatible with controllers that support a temperature-based input, so when designing a new system it is worth agreeing this in advance, so the sensor can be used to its full capability.
