Notes on the presence sensor:
• The body to be detected must have a temperature differ-
ent by more than 4°C (+/-) from room temperature
• If the body to be detected has a temperature very differ-
ent from the ambient T°C, the detection distance and the
opening angle may be higher than the values indicated in
the table above.
• Sources of intense heat can blind the sensor
• The sensor will have trouble detecting through a window
(IR diffraction)

The brightness measurement is a subjective measure representative of human perception given as 100%.
100% representing full daylight and 0% complete darkness.
