I have a setup where I have a 12V source and a PIR sensor like the one pictured (below) and some LED strips that are rated at 12V that I've mounted under the stair railings. The problem I've hit is that the pir sensor only outputs 3.3V when triggered.
In extreme simplicity (and horror) here's the setup I have:
The sensor - Here's the details page about it.
The infrared sensor operates on a voltage range from 5-20v, but only outputs 3.3V when triggered. The LED strips I have are rated at 12V (though I have tested them to work as low as 7.6V).
By searching around I've gathered that I need to turn up the voltage somehow or get more voltage running through the sensor. I've tried various step-up modules (this is one of them), but most require at least 3.5V and above to work correctly. Is there a way to have the sensor output more than 3.3V when triggered or some other way to make this setup work?
PS: I'm not an electrician, so I appreciate layman terms. I do understand logic though.
PS2: I've read this question, but didn't quite get what the accepted answer suggested.
