Boardoza SM351LT Magnetoresistive Sensor Breakout Board
The Boardoza SM351LT is a high-sensitivity magnetoresistive 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. Model: Honeywell SM351LT Voltage Supply: 3.3V - 5V Voltage Input Type: 3-pin 2.50mm header Current Consumption: 150µA Sensor Type: Magnetoresistive Sensor Output Type: Push-Pull (No external pull-up required) Operate Sensing Range: Typical: 7 Gauss Operating Temperature: -40°C to +85°C Board Dimensions: 20mm x 20mm
