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?
Key Measurement Parameters
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.
Communication, Power Supply and Design
* The manufacturer declares up to 10 years of operation for EU868 with a 10-minute reporting interval and a temperature of 25°C. Actual battery life depends on configuration, transmission conditions and the operating environment.
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.
