508E All-in-One Agricultural Soil Sensor: Measures soil temperature, volumetric water content, and salinity.

The 508E Soil Sensor is a multi-parameter monitoring device designed for the agricultural IoT and environmental monitoring sectors; it simultaneously measures three key indicators: soil temperature, volumetric water content, and electrical conductivity (EC). By capturing real-time soil data, it helps users assess soil conditions, thereby facilitating precision irrigation, scientific cultivation, and intelligent farm management.

Featuring a low-power design and RS485 Modbus communication, the sensor connects easily to data acquisition terminals, agricultural monitoring systems, and cloud platforms, making it suitable for a wide range of applications, including open-field farming, greenhouses, polytunnels, and ecological monitoring.

508E Soil Sensor Product Advantages

Integrated Multi-Parameter Monitoring

Traditional soil monitoring often requires installing multiple devices to measure different parameters; the 508E soil sensor, however, integrates multiple measurement functions into a single unit.

A single device simultaneously captures:

Soil temperature
Soil moisture
Soil electrical conductivity (EC)

This reduces the number of devices to be installed, improves monitoring efficiency, and lowers system deployment costs.

Low-Power Design, Ideal for Long-Term Outdoor Installation

Agricultural monitoring typically requires devices to operate over extended periods, making power consumption and stability critical factors.

The 508E soil sensor features a low-power design, operating on a DC 6–24V power supply with a power consumption of ≤0.05W and an average operating current of less than 3mA, meeting the demands of continuous, long-term monitoring.

Additionally, the sensor supports an automatic sleep mode-updating data every 5 minutes by default-to minimize energy consumption while maintaining monitoring performance.

RS485 Modbus Communication for Easy System Integration

To meet the data transmission requirements of agricultural IoT systems, the 508E soil sensor utilizes an RS485 communication interface and supports the standard Modbus RTU protocol.

Users can connect the sensor to data loggers, automated irrigation systems, or agricultural cloud platforms to enable remote data viewing and intelligent management.

Soil Sensor Installation Guidelines

To ensure measurement accuracy, the probe must maintain full contact with the soil during installation. Additionally, the installation site should be free of large rocks or plant roots that could interfere with the readings.

Furthermore, accurate measurement of soil moisture and EC requires the soil temperature to be above 0°C. For EC measurements specifically, a volumetric water content (VWC) of greater than 20% is also required to ensure data stability.
