MFR-NODE: Multifunction Research Node

The MFR-NODE has been designed to provide flexible communication, sensor and power options. The MFR-NODE supports SDI-12 and up to four 32-bit dry-contact counting digital inputs and two differential / four single-ended analogue inputs, with selectable 12V, 5V or 3.3V excitation. The MFR-NODE supports sensors with higher power requirements; a solar panel can charge either the internal lithium-ion battery or both the node and sensor can be powered by an external DC power system (e.g. battery or mains source).

Cat-M1 provides the option for remote installation and for areas outside the range of existing LoRaWAN networks.

The MFR-NODE has an onboard SD-Card to provide data logging capabilities and full data redundancy in the event of temporary loss of communications or dropped packets – ideal for research applications.

Data is stored in CSV format for ease of use.

LoRaWAN provides capability for full remote configuration through downlinks, including enabling/disabling confirmed messaging and changing the report interval.
