Indoor PIR in the kitchen

[jsg_85]

Hi guys

Wondering if you could help.

I wanted to fit an indoor PIR sensor in the kitchen which would control 20 led down lights.

My kids have a bad habit of leaving the lights on and leaving the room.

Is this possible? Can anyone send me a link to any good ones? How easy are they to fit?

Any advice would be much appreciated.

Thanks Jay.

The PIR is basically a movement/heat operated switch which would need to be, in simple terms, a replacement to the manually operated one.
Not a difficult install and no likely problems with loading or lack of it.
However,
Things to consider would be position of PIR sw; how to get the necessary wiring to it to provide correct safe operation, the necessary electrical and mechanical protection;
Would the PIR sw be a simple replacement or would it be able to interact with the manual switch.?
If these questions are not upmost in your design then it might be expedient to find a competent electrician

I fitted 4 flush pirs indoors for convenience and safety , electricity cost not so much an issue now with led

Top and bottom landing , toilet and half of kitchen. Best addition ever to house wiring imo.

Simple enough job but you need a spark to evaluate operation , pir rating and safety etc

I was also wondering how many hours of usage would have to be saved to pay for the PIR...

You could look at something like this as a straight replacement for your light switch, if it is 1-gang.

Now that PIR device would be about the simplest solution for our OP.

Need to check the back box for that

Supplied with a pp3 battery -would put me off

Says it fits in a 25mm back box, and/or has an extender. But many alternatives either need a neutral and/or won't switch LED lighting. So I guess some compromises might be needed. Or just wait for the kids to grow out of their "forgetfulness".

UK lighting design seems to be so constrained by the lack of neutral at the switch, will it ever change for the masses? And so difficult to retro-fit. I'm abroad, I have neutral in all my light switches as the cables came up from the floor to the switch, then up to the ceiling.
