The IoT Sensor Node is the field's central sensing hub — one ESP32-based enclosure with four interchangeable, weatherproof probes plugged in below it. It reads soil moisture, soil EC, soil pH, air temperature and humidity (plus light and rain where fitted) every few minutes and radios the readings to the nearest gateway over LoRa, so the rest of the system always knows exactly what's happening in that field.
