    Description

    EM500-SMTC Description

    Overview

    The EM500-SMTC measures soil moisture, temperature and electrical conductivity (EC) in a single buried probe, transmitting data over LoRaWAN for precision agriculture and environmental monitoring.

    3-in-1 Soil Insight

    Combined moisture, temperature and EC readings help optimize irrigation, fertilization and crop health decisions remotely.

    Field-Ready Probe

    IP68-rated probe withstands burial in soil while the EM500 transceiver provides long-range wireless backhaul and decade-long battery life.

    Industry Applications

    EM500-SMTC Industrial Applications

    Precision Agriculture

    Irrigation schedules adapt to real soil moisture and EC levels across fields and orchards.

    Greenhouses

    Substrate monitoring in pots and beds maintains optimal growing conditions with minimal manual sampling.
