Sensor lighting is an upcoming topic in the world of lighting. Now that LED is maturing in the development cyclus, new ways of extra energy savings are searched for. Of course, LED lighting will consume less and less energy with new technologies yet to be found, but the amount of clients that realize that sensor lighting is also an efficient way to save even more energy is steadily growing. To start with, we can distinguish two different types of sensors: motion sensors and daylight sensors.
What does a motion sensor do?
As the name reveals, motion sensors react to movement. Motion sensors have an accurate way of detecting movements by making use of infrared radiation, which shows warmth of objects. Microwaves can also be used for movement detection. In most cases, it is possible to adjust the time that a lamp emits light after movement is detected.
What does a daylight sensor do?
Daylight sensors on the other hand, constantly measure the amount of natural light in the application area. The moment this amount is too low, for example when it’s getting dark outside, lighting will automatically switch on. This can be a hard line: on or off, but fading in is also possible nowadays.
Both of these sensors have their own popular ways of application. This makes choosing the right sensor rather easy. Let us show you the differences of usage, placing and energy saving per sensor. We first distinguish the spot of placement: indoors or outdoors.
How to apply sensors outdoors
Outdoor sensor lighting is by far more popular compared to indoor lighting. This applies to companies as well as individuals. Most important reason for this is safety: outdoor sensor lighting is mostly used as a warning for unwanted visitors, to scare these visitors off, or just to make returning home more safe.
Outdoor motion sensor lighting is often placed at front doors, in gardens or on driveways. It makes coming home and parking cars or bikes easier and more safe. It is also used in parking lots, as street lighting or at entrances of companies.

How to apply sensors indoors
Indoors, motion sensors are more used as night lights, in bedrooms or hallways for example, or in stair cupboards. But also in offices or warehouses, this type of lighting is popular. As you can imagine, especially in offices or warehouses, motion sensor lighting can be very energy efficient because it makes constant lighting unnecessary. For example in warehouses, sensors can detect employees and light only their area. If employees move, unnecessary lights turn off and necessary lights turn on.
As for daylight sensors, indoor application is not very common yet. But it is possible to place useful daylight sensors inside. An example of this are LED panels close to windows in offices. These panels can dim during day and light up when employees are still working but the night starts to fall. For this, DALI controled panels are needed. This results in extra energy savings, since panels don’t have to be on full power all the time.
