Solar Wall Lamp Controller Board With Infrared Human Motion Detection – 3.7V Sensor Module For Garden, Porch & Security Lights

About This Product

This little controller board is the brains for a DIY solar wall lamp project.
It's got a smart infrared human motion sensor that picks up movement within 2 to 5 meters, so your light only turns on when someone's actually there – which saves battery big time.

It runs on a 3.
7V lithium battery with built-in overcharge and over-discharge protection, so your battery stays safe.

If you want to use a 3.

2V battery instead, just make sure it has a protective board attached.

The controller gives you three lighting modes: highlight + dim, highlight + off, and constant light – so you can choose what suits your setup.
The PCB measures about 59x19mm, compact enough to fit inside most wall light housings.
Use it for garden lights, pathway illumination, porch security, or garage lighting – anywhere you want automated, motion-triggered lighting.
It's a neat little module for tinkerers and solar project builders.
Comes with the sensor board and basic connections.
