Where the IoT Sensor Node covers moisture, EC, pH and air conditions all at once, the Soil Moisture Sensor Node does one thing at the lowest possible cost per point: track soil moisture and temperature continuously, so you can afford to place far more of them across a field and see variation between rows, not just one reading per zone.
