Tissue box covering PIR sensor at work

My current office is in one of those building that tries to be smart. Environment zones, clever air circulation, automatic blinds etc. One of the things it does is turn the lights off in each room when nobody’s there. Now the rooms also have light switches, so you can turn the lights on or off by yourself if you need to or want to.

Except my room. The lights are controlled by a PIR sensor in the ceiling, and that’s it. The lights come on when someone is in the room, whether you like it or not. And there are 8 light fittings, each with 4 bulbs in the room: 32 light bulbs + gallons of sunlight for one person seems rather excessive to me.

The solution: an empty tissue box and four sticky dots.
