LED Flood Light PIR sensor upgrade

[GeoTinkers]

Hi all. New here so be easy on me

I bought an exterior flood light off amazon made by Lutec 80W “9000” lumen supposeldy. Love the light itself because it has three adjustable heads and lights up an area that I need. Here is the issue i am having its PIR motion sensor kicks the light on every 40 seconds or less, its random. Called customer service and the whole 9 yards and they told me that it could be because the air temperature is cold, wether true or not why would they sell a floodlight in the North East Coast.

So I gave up with them and money was refunded and i am sitting on a good light with a bad sensor.

I opened the sensor itself and it has black, red, white and a yellow wire soldered to a circuit board. Anyone have a clue where I can get a sensor for this light that is not so sensitive , all the amazon ones have three wires and none have the fourth yellow wire. I will attach some pics of the light.

Any help is appreciated.

thank you

I suggest that you bypass the sensor so that the lamp stays on the whole time, and then supply the lamp via a separate PIR sensor.

I put in a couple of PIR lights about 5 years ago. One started to stay turned on when there was no movement so I did what I described and it's been fine since, The other identical one never needed modification and it's been fine.

So you dont think if i buy a sensor and solder it in it wont work? Could it be the quality of sensor you bought and went bad? Ive read a chinese company by the name of treewell makes decent ones. Just wanted some input and I was also thinking of doing something like you described but wish i could have the sensor integrated with the floodlight.

If you can find a replacement for the sensor circuit board, and solder it in, that will probably work.

However it is likely to be very difficult to find a circuit board as a spare part, or even a circuit board with a sensor that fits the housing and has the right connections.

There are lots of stand-alone sensors in their own housings that are mains powered and have a mains-voltage output, so it is easier to buy one of those, and fit it separately and connect the lamp via that. The only modification you need to do to the lamp is to make it turn on whenever it has power.

This one has 2 trimpots, so you can fiddle with sensitivity and delay for $2
