Lux Level Sensor

The sensors are typically used to monitor external lighting levels to optimise energy efficiency through dimming and or disabling lights as required.

Lux level sensor.

This is a nice simple non dimmable pir sensor available in an ip20 recessed version or an ip44 surface mount version. The built in interference filter in conjunction with the detectors spectral illuminance range. Lx is the si derived unit of illuminance measuring luminous flux per unit area. It is equal to one lumen per square metre.

External light level sensors tpvllo tpllo 40 00 internal light level sensor tpvllr tpllr 35 00 control solutions. 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. 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. 0 0 to 150000 lux.

Your motion sensor light will come preset to activate when it detects dusk and to deactivate when it detects dawn. 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. Hotel guest room comfort control.

As well as motion detection the sensor allows light level control which will operate from total darkness up to 65 000 lux.
