Dual-Probe Soil Moisture, Temperature & EC Sensor – Global NB-IoT

Model NA-DG-048
Price on request
A cellular soil sensor with two external probes on 2.5 m cables that measures moisture, temperature and temperature-compensated electrical conductivity (EC) at two depths or two points. It shows whether water and fertiliser reach the root zone, supporting irrigation scheduling and salinity control where no LoRaWAN gateway is available. It connects directly to NB-IoT networks worldwide and batches several readings into one uplink to stretch its 8,500 mAh battery. Settings and firmware are updated over Bluetooth, and NARA tracks both probes for every plot.
