Passive Infrared (PIR):
Detecting Heat Radiated from the Body
There isn't a right or a wrong technology, there's just the option that suits a specifi c lighting situation. The solution you choose all depends on what you want it to do.
PIR sensors in theory
Infrared sensors receive heat radiated from the human body. Segment lenses divide the detection zone into passive and active zones. This way, the highly sensitive sensors can detect persons or warm objects moving between the zones as a change in voltage. Even the smallest of movements are registered. The quality is governed by resolution (number of detection zones), design and the software.
PIR sensors in practice
Movements at right angles to the sensor (tangential movement) can be detected particularly well by passive infrared sensors. With radial movements, reach is usually shortened because detecting a change in temperature in this walking direction is more diffi cult. The point at which sensors are positioned should ensure they are not disturbed or distracted by
PIR sensors from STEINEL Professional
Developing our sensors, we pay attention to precision and reliability. Technological advances, such as multi-lens and multi-sensor technology, permit tremendous accuracy in reach settings and detection spectrum. Working with an exceptionally high number of switching zones, our sensors ensure precision and reliability.
Benefi ts of PIR
- Very good tangential detection
- .Detection reach and angle of coverage can be set with precision
- .High number of switching zones
- Also suitable for outdoors as only heat radiation is detected
- Twilight threshold and light 'ON' duration and detection zone can be set to suit individual needs
- .Electronic temperature compensation to avoid differences between winter and summer detection quality outdoors
