Triple-Probe Waterproof LoRaWAN Temperature Sensor

A waterproof outdoor node with three temperature probes, reporting all three readings over LoRaWAN. It measures temperature at three points at once — for example the top, middle and bottom of a tank, three shelves in a cold room, or supply, return and ambient on a chiller. Configurable temperature alarms flag readings outside the allowed range, and low power consumption keeps the node running on battery for long periods. NARA plots the three channels together, making gradients, stratification and failing equipment easy to spot.
