3.4 User Interface
Smartico Industrial Sensor LoRaWAN has several user interface components:
 LED Indicators for signaling
 User Buttons for waking up the device and launching Application functions
 Magnetic Sensor: to be used as a switch for external user actions, without a need to open the housing.
 Internal Communication Interface: it contains the serial interface (UART) and is used to device
configuration or update firmware.
Figure 3: Internal Communication Interface
If there is no data cable supplied by the manufacturer, the customer can make the cable himself. To communicate with
the sensor, it is enough to use any UART to USB converter and connect to three contacts (UART_RX, UART_TX and GND).
The pinout of the connector is shown in the Table 5.
