Radio temperature, humidity, differential pressure datalogger for DeepWave: wireless monitoring system based on LoRa (Long Range) for a very long distance transmission that allows to have only one Helios receiver to cover all systems. The Pluto module has an ePaper screen (like that of ebooks), 2 inputs for Smart Sensors chosen from those available, audible alarms via buzzer. The Smart Sensors (not included) are supplied with an Accredia traceable calibration certificate and allow immediate, economic and simple recalibration of the system, without intervention. Pluto also has the connector for external power supply (the batteries have a backup function, the power supply is not included). Batteries are easily replaceable by the user.
