4-Probe Soil Moisture, Temperature & EC Transmitter – Global NB-IoT

Model NA-DG-015
Price on request
A cellular transmitter that connects four soil probes, each on a 3.5 m cable, to measure moisture, temperature and temperature-compensated electrical conductivity at several depths or points from one unit. It reports over NB-IoT networks worldwide, so orchards, greenhouses and open fields can be monitored without installing a gateway. Several readings are grouped into one uplink to extend battery life. Choose an 8,500 mAh battery or a solar-charged version for long-term deployments. Configuration and firmware updates are done over Bluetooth, and NARA turns the profiles into irrigation and fertigation insight.
