I have a set of six matching PIR outside lights. They are all the same style and are no longer available.
On two of them the circuit board has developed a fault whereby the light level at which they become active works fine but once activated, the time for which they stay on has become infinite. There is no obvious dry joint on the circuit board and I have re-soldered all the joints that look as if they are possibly at fault. I have looked especially carefully at the R and C which deal with the timing.

The fault remains.

The circuit code is SW7005S but TBH i do not think it is meant to be user serviceable. I certainly cannot find any details about the board.

Does anyone know if there is a board that I can get which is

a) Mains powered and can run a mains LED
b) Has light level and on-time adjustment
c) Has a PIR sensor or similar to trigger them?

So are you asking for help with a repair (we'd need at least a good picture) or do you just want an off-the-shelf module to replace the one that has failed? "Both" is OK! Either way, we need more details. If you want a new module, you need to know the power level that is being controlled by the module. Voltage and current specs.

 

The circuit consists of a single circuit board, (picture to be attached) with power in. The live power to the light comes from the circuit board and the neutral is common.

The unit is badged to control up to 100W but as I use LED bulbs I only need to control about 10W.

There are mini-pots to control light level and time.
There is no spec available for the board that is in place.

 

What I think would be easiest would be a replacement board. There is plenty of room in the device. There is no dc supply to the device, only 220V ac
A direct replacement light is not available and If I replace the light with a different one, the new holes for mounting screws are likely to make the whole thing look a mess as the old mounting holes will not be hidden.

 

Any of the caps bulging at the top ?

Burnt or discolored resistors ? Or burn marks on PCB close to R ?

If this is outside weather related application water damage to pots ?

It could be weather related damage to pots-pcb but I have had a pretty good go at making sure everything is clean and the symptom remains the same. I suspect that pursuing a board level repair might be more time and effort than replacing the PCB would be.

 

Maybe something like this?

Thanks for looking. One of those devices needs an arduono and the other needs a dc psu. I have found this

Why do you think one of those items require an Arduino? I think that neither requires an Arduino. Not sure on the first item, but it looks like it doesn’t require an Arduino. Pretty sure the second doesn’t either.

And both require a DC power source.

Well the page I read said Arduino for first device however since they both require DC power supplies and I need 220V ac Neither of them work anyway. But as I said, thanks for looking.

Ok. The Arduino reference only meant that it could be used with an Arduino. I’ve seen many projects where an Arduino PIE sensor was used by itself. Good luck!
