The SM300D2 sensor supports connections via UART or RS485. This platform only supports UART-connections.
|
|
Make sure you have a :ref:`UART bus <uart>` in your configuration with the ``rx_pin`` connected to the
|
|
TX pin of the sensor. The sensor does not support receiving data, so the ``tx_pin`` does not need to be
|
|
connected. The sensor expects the baud rate to be set at 9600.
