Product Description The 3.7V/3.2V Solar Lamp PIR Motion Sensor Board is an advanced, all-in-one controller designed for creating or repairing high-efficiency solar-powered security lights. This board integrates solar battery charging, PIR motion detection, and intelligent lighting control into a single compact PCB. It supports both standard 3.7V Li-ion and 3.2V LiFePO4 batteries, providing flexibility for different energy storage needs. The included remote control allows users to switch between multiple lighting modes, such as "Always On," "Motion Triggered," or "Dim to Bright," making it perfect for garden paths, doorways, and outdoor wall lamps.
Key Highlights
Dual Battery Support: Intelligent circuit design is compatible with both 3.2V LiFePO4 and 3.7V Li-ion batteries without manual switching.
Three Intelligent Modes: Choose between full-on at night, dim-light with motion sensing, or off-to-on motion sensing for maximum energy saving.
High Sensitivity PIR: Features a wide-angle infrared sensor that detects human movement up to 10 meters away, ensuring timely security lighting.
Built-in Protection: Includes integrated over-charge and over-discharge protection to extend the lifespan of your lithium batteries.
Wireless Remote Included: Allows for easy mode adjustments and power control without needing to disassemble the lamp housing.

Installation Tip from Robogears This board is designed for outdoor lighting; ensure the PIR sensor (the white dome) is exposed through a hole in your project enclosure for it to function. Connect the battery first before connecting the solar panel to allow the IC to initialize. Since this board does not have a separate light sensor, it uses the solar panel voltage to detect "night" (when the panel stops generating power). If your lamp stays off during the day even in "Always On" mode, this is a normal battery-saving feature.
