In photometry this is used as a measure of the intensity as perceived by the human eye of light that hits or passes through a surface.
Lux level sensor.
Lux light level adjustment.
The sensors are typically used to monitor external lighting levels to optimise energy efficiency through dimming and or disabling lights as required.
The built in interference filter in conjunction with the detectors spectral illuminance range.
Your motion sensor light will come preset to activate when it detects dusk and to deactivate when it detects dawn.
Lx is the si derived unit of illuminance measuring luminous flux per unit area.
It is analogous to the radiometric unit watt per square metre but with the power at each wavelength weighted.
As well as motion detection the sensor allows light level control which will operate from total darkness up to 65 000 lux.
0 0 to 150000 lux.
The external light level sensors return a linear 0 10vdc signal representing the lux level at the photo diode cell based on the selectable lux levels.
External light level sensors tpvllo tpllo 40 00 internal light level sensor tpvllr tpllr 35 00 control solutions.
You can set the time delay from 2 seconds to 15 minutes.
Hotel guest room comfort control.
It is equal to one lumen per square metre.
