The Pyro Sensor
This electric module reacts as soon as the infrared thermal radiation within the detection zone changes. This causes a voltage jump which is then converted into an electronic impulse, which switches the light on or off.
Heat Radiation
Due to their body temperature humans radiate heat. Infrared technology uses this radiation to detect motion and to react accordingly.
Reach
The reach of infrared sensors depends on the direction of movement. With tangential movements (parallel to the sensor) the reach is about 12 m on average, which is shortened when moving directly towards the sensor (radial movement). To attain the maximum reach the optimal mounting height of 2 m should be given.
