Lighting Sensors & Detectors

Lighting Sensors and Detectors for Automatic Light Switching

Lighting sensors and detectors are designed for automatic light control in spaces where the light does not need to remain on continuously. They are used to switch on lighting when movement, presence or changes in ambient light conditions are detected. This solution is useful in corridors, staircases, entrances, garages, wardrobes, sanitary rooms, technical rooms, warehouses and outdoor parts of a building. When planning a complete system, it is also useful to check the parent category Power Supplies, Sensors and Controllers, where products for powering, detecting and controlling LED lighting are grouped.

Motion Sensors, Presence Detectors and Light Sensors

A motion sensor for lights detects movement within its operating range and is suitable for spaces where people stay for a shorter period of time. A presence detector is useful where detection of smaller movements or longer presence is important. A light sensor or brightness sensor enables lighting control according to the amount of natural light. When choosing a product, it is necessary to check the range, detection angle, maximum load, voltage, operating time and sensitivity adjustment options.

PIR and IR Motion Sensors

A PIR motion sensor, or infrared sensor, is a common choice for corridors, entrances, staircases, wardrobes and indoor spaces. An IR motion sensor is used in systems where movement detection within a specific area is important. When choosing a sensor, the sensor type is not the only important factor; the installation location, detection direction, mounting height and switch-on time setting are also important. If the sensor is part of a system with light regulation or remote control, it is useful to match it with products from the Controllers and Dimmers category.

Recessed, Surface-Mounted, Wall-Mounted and Ceiling-Mounted Sensors

Lighting sensors differ by installation method. A recessed motion sensor is suitable for more discreet installation in a ceiling, furniture or prepared opening. A surface-mounted motion sensor is installed on the surface and is useful where recessed installation is not planned. A wall-mounted motion sensor is suitable for entrances, corridors and passageways, while a ceiling-mounted sensor provides more even detection within a room. In indoor projects, sensors are often combined with products from the Indoor Lighting category, while discreet solutions can also be combined with products from the Recessed Lights category.

Dusk Sensors, Photocells and Outdoor Sensors

A dusk sensor, daylight sensor or photocell for lights allows lighting to switch on according to the brightness of the surroundings. These solutions are useful near entrances, courtyards, garages, gardens, facades and outdoor passageways. An outdoor motion sensor or outdoor light sensor must be selected according to the installation location, product protection rating and usage conditions. When planning outdoor lighting, it is useful to connect sensors with products from the Outdoor Lighting category, while near entrances and facades they can also be combined with solutions from the Outdoor Wall Lights category.

Use on Stairs, in Bathrooms, Wardrobes and Passageways

Motion sensors are useful where quick and practical light switching is important without using a manual switch. In wardrobes and storage rooms, they improve visibility; in corridors and passageways, they reduce unnecessary light operation; and on stairs, they help provide safer orientation. They can therefore be combined with products from the Stair Lighting category. In bathrooms, sanitary rooms and spaces with moisture, the technical properties of the sensor must be checked carefully, while broader planning of such spaces is also related to the Bathroom Lights & Ventilation Fans category.

What to Check Before Purchase

Before purchasing, check the sensor type, range, detection angle, installation method, voltage, maximum load, time setting, sensitivity, light threshold and suitability for indoor or outdoor use. For sensors used with LED lights, compatibility with the selected light is important, while outdoor models require appropriate protection. A well-chosen sensor for automatic light switching helps lighting work more practically, efficiently and in a way that is better adapted to the space.
