Mercury radio module of the LoRa DeepWave system: large ePaper screen (same as the one of ebooks), 2 connectors for Smart Sensor chosen from those available (temperature, humidity, differential pressure, light), local sound alarms via buzzer. The Smart Sensors (not included) are supplied with an ISO calibration certificate and allow fast, economic and easy recalibration of the whole system, without external intervention. Mercury mounts an external antenna also. DeepWave solution is based on the Lo.Ra. (Long Range) radio protocol which allows transmission over very long distance and requires only one Helios receiver to cover all nodes. Batteries are easily replaceable by the user.
