OK-TG10-3+ Soil Moisture Monitoring System

Product Introduction
The OK-TG10-3+ Soil Moisture Monitoring System is designed for long-term monitoring of soil moisture and temperature at multiple depths. Using Frequency Domain Reflectometry (FDR), it provides dynamic soil condition data to support precision irrigation, agricultural water management, and environmental research.
Its tubular design houses the sensors inside a protective PVC casing, reducing direct contact with soil and helping minimize interference from soil salts, fertilizers, pesticides, and irrigation activities. Powered by a solar panel and built-in rechargeable lithium battery, the system integrates 4G wireless communication for remote data transmission and supports RS485 communication for integration with external monitoring equipment.

Performance Features
• Multi-Depth Monitoring: Measures soil moisture and temperature at different soil layers, with selectable measurement spacing of 10 cm or 20 cm.
• FDR Measurement Technology: Uses dielectric-based frequency domain reflectometry for rapid soil moisture measurement.
• Non-Contact Sensor Design: Sensors are housed inside a PVC tube to reduce direct soil contact and protect internal electronics.
• Real-Time Monitoring: Provides timely soil moisture and temperature data for irrigation decisions.
• Solar-Powered Operation: Combines a solar panel with a built-in rechargeable lithium battery for outdoor deployment.
• 4G Remote Data Transmission: Sends field measurements to a cloud platform for remote monitoring.
•RS485 Communication: Supports standard Modbus-RTU RS485 communication for integration with compatible data acquisition systems.
• Low-Power Design: Supports extended field operation with reduced maintenance requirements.
• Durable Protection: PVC housing and rated protection against water and dust support demanding outdoor environments.
• Flexible Power Input: Supports DC 10–18 V input.

Working Principle
The OK-TG10-3+ uses Frequency Domain Reflectometry (FDR) to estimate soil moisture by measuring changes in the soil's dielectric properties. Because water has a different dielectric response from most soil components, variations in the measured electrical characteristics can be used to determine soil moisture.
Temperature sensors monitor soil temperature at the installed measurement depths. The system collects readings from multiple soil layers and transmits the data through RS485 or its integrated 4G module. This allows users to track changes in soil conditions and develop irrigation schedules based on actual field measurements.
