Lux Level Sensor

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.

Lx is the si derived unit of illuminance measuring luminous flux per unit area. Hotel guest room comfort control. Your motion sensor light will come preset to activate when it detects dusk and to deactivate when it detects dawn. You can set the time delay from 2 seconds to 15 minutes.

Lux light level adjustment. External light level sensors tpvllo tpllo 40 00 internal light level sensor tpvllr tpllr 35 00 control solutions. 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. The ms 020s o and ml 020s i illuminance sensors are both all weather sensors having customized detector sensitivities for either indoor low light level or outdoors high light level applications.

0 0 to 150000 lux. The built in interference filter in conjunction with the detectors spectral illuminance range. The light level adjustment controls the amount of natural light that starts operations and stops the motion sensor light from triggering when the sun is up. 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.
