EM500-SMTC — Soil Moisture, Temperature and Conductivity

Milesight EM500-SMTC with the MEC20 probe is a wireless measurement system designed for continuous monitoring of conditions in the soil.

A single probe measures moisture, temperature and electrical conductivity (EC), providing data useful for assessing plant growth conditions, optimising irrigation and monitoring changes occurring in the substrate.

Three Key Soil Parameters at One Point

3-in-1 Measurement

A single probe monitors soil moisture, soil temperature and electrical conductivity, reducing the number of required measurement points.

Design for In-Ground Operation

The MEC20 probe has an IP68 protection rating and is made from corrosion-resistant materials, allowing it to operate directly in soil.

Wireless Transmission

LoRaWAN enables results from distributed outdoor measurement points to be transmitted to a central system without the need for wired communication infrastructure.

Where Can the EM500-SMTC Be Used?

Smart Agriculture
Automatic Irrigation Systems
Greenhouses and Protected Crops
Orchards and Plantations
Horticulture
Green Area Monitoring

Irrigation Based on Actual Soil Conditions

Continuous moisture measurement makes it possible to observe the actual soil condition instead of basing irrigation control solely on a time schedule.

Data from the EM500-SMTC can be used to determine when to start and stop irrigation, reducing both substrate drying and unnecessary water consumption.

Additional Information About Conditions in the Substrate

Range up to 20 000 µS/cm

The probe enables electrical conductivity measurement over a wide range, making it possible to observe changes in this parameter over time.

Change Monitoring

Regular EC measurements can support observation of changes related, among other factors, to the content of dissolved salts and the method of fertilisation and irrigation.

Data in One System

Conductivity can be analysed together with soil moisture and temperature, providing a more complete view of conditions at the measurement point.

Design Prepared for Demanding Conditions

IP68 Probe

The measurement module is designed to be buried directly in soil and operate continuously in an environment with high humidity.

IP67 Transmitter

The external communication unit is protected against dust and water, allowing it to be mounted directly in outdoor installations.

Flexible Mounting

The transmitter can be mounted on a wall, pole or DIN rail, while the probe is installed directly in the monitored soil.

Local Storage and Alarming

1000 Records

The device can locally store up to 1000 measurement records.

Retransmission

Data stored during temporary communication loss can be retransmitted after the network connection is restored.

Threshold Alarms

The EM500-SMTC supports threshold alarms and a temperature change alarm, allowing unwanted conditions to be detected more quickly.

EM500-SMTC in a Crop Monitoring System

Data from the probe can be transmitted via LoRaWAN to a gateway, and then to a supervisory platform. This makes it possible to centrally monitor soil conditions, build measurement history and use the data in smart irrigation systems.
