Lux Level Sensor

Lx is the si derived unit of illuminance measuring luminous flux per unit area.

Lux level sensor.

Your motion sensor light will come preset to activate when it detects dusk and to deactivate when it detects dawn. The sensors are typically used to monitor external lighting levels to optimise energy efficiency through dimming and or disabling lights as required. You can set the time delay from 2 seconds to 15 minutes. 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. Hotel guest room comfort control. This is a nice simple non dimmable pir sensor available in an ip20 recessed version or an ip44 surface mount version. 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.

It is analogous to the radiometric unit watt per square metre but with the power at each wavelength weighted. It is equal to one lumen per square metre. As well as motion detection the sensor allows light level control which will operate from total darkness up to 65 000 lux. 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.
