:name: SM351LT Magnetoresistive Sensor
:relevant-api: sensor_interface
Detect a magnet's presence using the SM351LT magnetoresistive sensor (polling & trigger mode).
Overview
********
This sample application periodically polls an SM351LT magnetoresistive sensor
and displays if a magnet near to the sensor, via the console.
Requirements
