OverviewDifferent types of sensors

Motion Detectors - OutdoorsWatching over outdoor areas and buildings, for controlling lights efficiently. Wall, ceiling and corner mounting possible.

Motion Detectors - IndoorsWatching over thoroughfares in buildings, for controlling existing lights efficiently. Wall, ceiling and recessed versions possible.

Presence Detectors - IndoorsUltra-precision surveillance for common and highly frequented areas in buildings. Light only 'ON' when someone is present, automatic constant lighting control and dimming function. Can also control HVAC, KNX or Dali systems.

OVERVIEW

SensorLights - OutdoorsCombined systems of light plus integrated sensor.

SensorLights - IndoorsCombined systems of light plus sensor for use in buildings, for passageways and corridors, for WCs, cloakrooms, stairwells etc.

Sensor-Switched Floodlights - OutdoorsInstantaneous bright light as soon as movement is detected. LED or halogen, all areas around buildings.

PIR Basics

PIR (Pyroelectric Infra Red)

PIR Basics

• The PIR is a passive system: only a receiver!• The PIR receives infrared rays and therefore only reacts to radiated heat• The PIR is therefore a heat sensor ( pyrosensor )• The PIR sensor needs movment

Pyroelectric infrared motion detectors (PIR): What is important ?

PIR BasicsWhat is important about the movement?

Tangential movement Radial movement

Factors that influece the range of a PIR sensor system:PIR Basics

• Size of the object emitting radiation

• Temperature difference between the object emitting radiation and the environment, where the following applies: the greater the temperature difference, the further the reach

• Weather influences such as rain, snow and fog, etc...

• The direction of movement of the object emitting radiation

• The speed at which the object moves through the detection zone

• TIP: Locate PIR sensors with a clear line-of-view of the area to be covered. Place the sensor perpendicular to likely movement, as a person is most easily detected when crossing the boundary between one Fresnel lens element and another.

PIR LensWhat are the different types of PIR lenses?

Fresnel Lens Sensors Multi-Lens Sensors

Active area

Infrared radiation from this area is picked up by the pyro detector

Passive area

The detector is „blind“ for this area

•Max. 12m ( depending on the premises and surrounding conditions ) - in the tangential walking direction

•To be reduced to up to 2m by pivoting the sensor

•Detection zone individually adjustable by shrouds

Fresnel Lens

Augustin-Jean Fresnel was a French engineer who contributed significantly to the establishment of the theory of wave optics. Fresnel studied the behaviour of light both theoretically and experimentally. He is perhaps best known as the inventor of the Fresnel lens, first adopted in lighthouses while he was a French commissioner of lighthouses, and found in many applications today.

HF basics

HF (high frequency)

HF radar

HF sensors

High frequency sensor (HF): What is important ?

HF basics

• The high frequency sensor is an active system: transmitter and receiver!

• The transmitter of the high frequency module sends electromagnetic waves and receives the echo reflected by walls and objects.

• If there is no motion in the detection zone, the reflection echo is constant and the electronics do not switch any light ON

High frequency sensor (HF): How does it work?

HF basics

The third common tecnnology is high frequency (HF) ultrasound or ultrasonic sensors. HF works exactly the same as a bat's "radar" or a submarine's "sonar." The sensor sends out a high frequency sound wave that bounces around the space and returns to the sensor. Any movement that disturbs the wave activates the sensor. HF sensors can be very sensitive and can read through many materials including the most commonly used interior construction materials and glass. From a human occupancy standpoint, HF's big limitation is that it responds to any motion, not just human presence. For example, an open window and rustling curtains or a moving window shade or, in an office environment a piece of paper coming out of a printer, can activate an HF sensor even if no one is there.

HF basicsInterference with different materials• Steel concrete (20 cm thick): approx. 90 %

• Sandwich wood wall (8 cm thick): approx. 10 %

• Office cabinetry wall (2 x 40 cm thick): approx 30 %

Advantages of HF sensors:

HF sensorlights

• No more searching for the switch, Light comes on automatically indoors

• Prompt light in response to movement

• Peace of mind, convenience and energy saving; because of latest HF-Sensor Technology

• Looks like a „normal“ interior lamp, HF-Sensor is concealed behind the glass shade

Using the right sensor

Motion vs.

presence

Motion detectors:

Detection: Walking movements

Application: •Indoors and outdoors•Indoors: garages, corridors, storerooms•Outdoors: driveways, entrances, car parks, carports, fronts of buildings•Motion detectors provide convenience, safety and security

Motion vs. Presence detectors

Presence detectors:

Detection: Even the tiniest movement, also sedentary activities

Application: •Offices, classrooms, conference rooms etc.•High rooms: warehouses, sports halls etc.•Additional control of heating, ventilation, air-conditioning or constant lighting control•Presence detectors provide maximum energy efficiency and convenience

The most important issue for a successful occupancy sensor installation is to understand the strengths and limitations of each type of sensor and to choose the appropriate sensor for the application. Occupancy sensors can save significant amounts of energy and take the human factor out of remembering to turn off the lights, the air conditioner and any other equipment that only needs to be on when there is human presence.
