Light sensor

Written by stephen gale

We now have a light sensor connected to the lighting computer.  This means that we can programme the lights so that they come on after dark and turn off during the day.

It is another relatively cost effective piece of kit from Loxone.  The main issue was climbing on the roof to fix it in position.  We have sited it on the small apex at the rear of the property (away from any street lighting or security floodlights).

It is connected to the Loxone kit using Cat5e cable.  One pair of wires is used to supply it with 24v.  Another pair of wires send back data on the light level (as a 0-10v signal).  This is then connected to one of the Loxone’s analogue inputs.

The sensor is positioned high up on the small gable end in the extension.  This is away from any light from street lighting or from the security light at the front of the building.

Inside the lux sensor.  Orange and orange/white used to supply 24v and green and green/white for data.  It then simply supplies a 0-10v signal to the Loxone kit based on the amount of light outside.  The dip switches can be used to adjust it's sensitivity.

  1. Hi. Which lux sensor is this? Where did you buy it?

    • This was the standard LUX sensor that you could buy for the Loxone mini server. I just checked on the Loxone website and I can’t see it listed anywhere. It was really easy to connect and a good solution. I can only suggest contacting Loxone and to find out how you can purchase one (or an equivalent).
