Steinel

The basic idea with the control of lighting based on sensor technology is that the sensor will activate the lighting when it detects motion in the monitored area and that once the motion stops, the lights will turn off automatically after a specified time. The sensor’s daylight level switch directs the lights only to be illuminated by motion when below a specified lux value.

Steinel sensor technology solutions can be applied to all modern control systems (DALI, KNX, DIM standard light, COM1 and COM2). Reliable sensor solutions require different sensor technologies to be used in different rooms of a building. Office space, meeting rooms, stairways, lobbies, parking garages and outdoor areas and stall spaces each set their own requirements for choosing the sensor technology. Steinel's sensor technologies are PIR, HF, iHF, US, Digital HF True Presence® and optic detector (HPD2). The product selection includes both sensors and sensor lights.

Office spaces and meeting rooms

The best sensor technology for office spaces and meeting rooms is ultrasonic (US) technology. The US sensor is so sensitive that it can detect the lightest of movements, such as the use of a keyboard. The sensor does not need a direct line of sight to the person. The ultrasound waves can be restricted to a specific room, as long as the doors are closed. If the door is opened, the waves also spread to the adjacent room if within the sensor range. US is equally good at detecting vertical and horizontal motion. The quality of ultrasound recognition does not depend on the direction of the motion. Temperatures do not affect recognition with ultrasound technology.

Hallways and lobbies

The best suited sensor technology for hallways and lobbies is high frequency (HF) recognition. When there is motion in the space, it triggers an activation signal. HF offers practically seamless motion detection indoors. The HF sensor serves as an active system completely independent of temperatures. Due to the radio waves, a HF sensor is also able to detect motion behind glass, wood and thin walls. It is also suitable for public restrooms, for example, because HF signals can penetrate thin walls.

Yard areas

Suitable recognition technologies for outdoor applications include both PIR (passive infrared recognition) and iHF (intelligent high frequency recognition). PIR recognises warm objects, such as people and cars, but not cold ones, such as the motion of trees and bushes. iHF reacts to all motion and is able to differentiate moving and motionless objects very accurately Motionless objects, such as trees and bushes, do not then result in “false activations”.

Tall rooms

In tall rooms, such as warehouses and sports centres, the most effective detection technology is PIR (passive infrared recognition), which is able to operate from a mounting height of up to 14 metres.

Parking garages

Both infrared sensors and high frequency sensors can be used in parking garages.

Steinel is a pioneer in sensor lighting technology. Steinel’s products include all of the necessary lighting technologies for all types of applications. A completely reliable detection solution can only be achieved through the simultaneous use of several sensor technologies.
