| :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 |
| ************ |
| |
| This sample uses the Honeywell SM351LT sensor. |
