EM500-SMTC Soil Moisture, Temperature,
and Electrical Conductivity Sensor

Engineered for reliable soil monitoring in harsh environments, EM500-SMTC accurately measures soil moisture, temperature and conductivity with long-term stability. Adopting low-power LoRaWAN® communication and a rugged, corrosion-resistant probe, it enables maintenance-free deployment and wireless data transmission. Paired with Milesight gateway and IoT platform, it supports remote real-time monitoring, data storage, alarm and easy configuration for precise agricultural and environmental management.

Application scenarios

Widely used in smart irrigation control, greenhouse monitoring, precision agriculture, smart horticulture and golf course maintenance for efficient soil condition management.

Application Case

◂ Pain Point▸

Lack of Real-Time Data: Isolated irrigation control systems used fixed timing schedules, ignoring real-time environmental factors (rainfall, soil moisture, temperature), leading to overwatering/underwatering, high water costs, and green space damage.

Redundant Manual Inspections: Existing hardware required manual programming, annual site visits for reprogramming and battery changes, increasing operational complexity and costs.

◂ Solution▸

eploy a LoRaWAN® smart irrigation solution to enable data-driven, automated irrigation:

EM500-SMTC Soil Moisture, Temperature, and EC Sensor: Buried at 5cm depth in sports fields to collect real-time soil data without disrupting play areas.

Weather Station: Provides complementary environmental data (rainfall, temperature) to calculate soil moisture deficits.

UC300 IoT Controller: Integrates with existing irrigation systems, receiving control signals from the data platform to start/stop irrigation via IF-THEN logic.

UG67 Outdoor LoRaWAN® Gateway: Provides city-wide LoRaWAN® coverage, aggregating sensor and controller data.

INDICIUM DataBus & IoT Platform: Collects, visualizes, and analyzes data; triggers irrigation control signals when moisture thresholds are reached, and integrates with council systems (e.g., Technology One) for task management.

Result

Enables real-time, condition-based irrigation to eliminate overwatering/underwatering, reduce water consumption and costs, minimize manual maintenance, and keep green spaces vibrant and usable for visitors.
