LoRa radio node for DeepWave wireless system: large ePaper screen (ebook type), 2 connectors for Smart Sensor to choose from those available (temperature, humidity, differential pressure, light), local acoustic alarms with buzzer. The Smart Sensors (not included) are supplied with an ISO calibration certificate (Accredia traceable) and allow immediate, economic and simple recalibration of the system. Saturn has an external antenna and power supply (the batteries have a backup function), as well as a relay output to connect if the instrument has to be activated when an alarm occurs. For example, it is possible to connect flashing lights, sirens or other. DeepWave is based on LoRa radio protocol (Long Range) for a very long distance transmission that allows to have only one Helios receiver to cover all the sensors. Batteries are easily replaceable by the user.
