Dual-Probe Waterproof LoRaWAN Temperature Sensor

A waterproof outdoor node with two temperature probes, reporting both readings over LoRaWAN. Two measuring points per device suit inlet and outlet pipes, supply and return lines, or a freezer and the room around it. Configurable temperature alarms flag readings outside the allowed range, and low power consumption keeps the node running on battery for long periods. On the NARA platform the two channels are shown side by side, so temperature differences across heat exchangers, pumps and cold chains are visible at a glance.
