To switch a piece of equipment off, we simply break the circuit from the source of power. A mains switch would work equally well in the live or neutral conductor, and this is known as single pole switching. However, a neutral switch leaves all internal mains wiring live, constituting an ...
A beam of light emitted from an LED passes through a transparent disk patterned with opaque lines, and is picked up by a photodiode array. The photodiode array (also called a photosensor) responds by producing a sinusoidal waveform which is transformed into a square wave, or pulse train. ...
Earthingis a fundamental safety system used in electrical installations. It works in co-ordination with circuit breakersMCBs,Fuses, andRCDsto ensure that an electrical supply can be disconnected quickly in the event of afault. This greatly reduces shock risk. Most houses have anearth connectionsuppl...
It was worth checking if it was a quick fix as I'm quite capable of doing basic things. I have already fitted one of these PIR ones in the kitchen and it is fantastic, but the wiring situation was different in that case and it replaced the wall switch. ...

I bought a light sensor for the bathroom which is IP rated for bathroom use to replace the pull cord. The idea is that walking into the room should activate the light, it also has a sensor so it will only turn off if it needs to (adjustable pot), same for the sensitivity and the ...
