Hi All,
First visit and first post, so hello and I hope everyone has had a great Christmas!
I'm hoping general discussion is the right place to start for my query?
We've had an LED lit and heated bathroom mirror my wife purchased from Ebay many years ago that has never worked correctly. The motion sensor continually activates the relay so it would constantly turn on and off (possibly partly due to the ceiling down light reflecting off the white sink back up into the sensor). Our long term fix has basically just been a bit of paper taped over the sensor so it doesn't activate at all. Major downside being its then just an expensive normal mirror... Minor down side being if we have a power cut or have to turn the particular power circuit off, it comes back in the on state and we then have the fun of trying to remove the paper wave hand to turn it off and get paper back in place before it turns back on again.
So today in post christmas boredom I decided to crack it open and see if there was a way I could replace the motion sensor with a simple switch instead, on opening it up it appears that the motion sensor is basically a IR LED and a light sensor, so 3 wires to the LED and two wires to the sensor, with my little knowledge I wondered if shorting the two wire coming of the sensor would activate the relay switching the LED light and heating circuit, unfortunately this isn't the case.
The current setup is based on https://www.cens.com/cens/html/en/product/product_main_114109.html and I'm wondering if there's a simple relay or direct switch I could put in its place instead? The output from the above goes to both a heating element on the back of the mirror glass as well as to an LED driver that drives the LEDs. So I'm guessing a simple waterproof switch and relay would be a straight forward way of replacing the never working motion sensor?
I have a great deal of experience with computer builds but not really electronics and wondered if anyone could suggest what might work here? I do appreciate given this is a bathroom mirror and water and electricity means I have to be sensible, the whole unit is sealed and any switch I install will need to be a waterproof switch.
Any advice much appreciated!
Best wishes,
Mike
P.S. I should point out I'm in the UK, so 240V mains power.
