The Boardoza SM351LT is a high-sensitivity hall-effect sensor module designed for lid, door, and drawer position detection. It features omnipolar sensing, activating with either pole of a magnet. With a push-pull output, the module eliminates the need for an external pull-up resistor, simplifying integration into various applications.

- Lid, Door, and Drawer Position Detection: Detects open/closed states using a magnet.
- Non-Contact Operation: Works through non-metallic surfaces, making it ideal for sealed enclosures.
- Omnipolar Sensing: Responds to both north and south poles of a magnet for flexible placement.
- Push-Pull Output: Built-in driver circuit eliminates the need for an external pull-up resistor.
- Dual LED Indicators: Includes Power Good LED (D1) and Output Indicator LED (D2) for real-time status feedback.
