Any way I could Re-wire this aids-tier motion sensing light to always stay on? v.wiringandshit

It is a cheap motion sensing light, the only on/off is the motion sensor. It barely works. Could I solder some of these wires together to always stay on? Don't know what to try :hs: :o

Put a desk fan on oscillate so it keeps moving and then the sensor will always see motion. Hackerman

edit: this is a more elegant solution than some common pinwheel

Someone explain to me why the motion sensor has PWM? Think the light dims on/off, or is there another reason for a motion switch to have PWM?

PWM sensor output can help to avoid current surge which can damage LED light fixtures.

If you want to disable the sensor, just bypass it. First, use a meter to test the red/black circuit on the sensor. Then, test the white/black circuit on the sensor while tripping the motion sensor. If the voltage on red/black is the same as white/black (while the sensor is being tripped) then just cut the red/white wires off the sensor board and jump them together to test. If this proves effective, then to do a cleaner installation, simply desolder the 3 sensor wires from the mainboard, then solder a jumper across the VIN/PWM pins (again, on the mainboard).

DISCLAIMER: If you burn your entire house down trying to achieve this outcome, don't come crying to me. I'm not liable for shit you decide to do. This is just what I would do if it was mine.

I'd risk dismemberment or death trying out your solution.

If you don’t have a voltmeter u can just lick the leads to check, if it tickles you got the right one

Trying this when I get home :x: :x: :x:

Clip off sensor side - strip and use a twist type connector on white and red. Attach black to a metal screw or other ground somewhere. Cleaner look - as mentioned above just jump a wire across those two after removing the old ones

First question: if it's modded to always stay on, is there any way to cut power to it? Like is it hardwired to the house where only a breaker would then be able to used to turn it off?

If it was me I'd try to get rid of the whole sensor system completely. What I mean is instead of faking that the sensor is always seeing motion, just get rid of anything that even relies on the sensor, just have power -> transformer -> LED -> ground and solder in some kind of switch somewhere in that circuit.
