Product name
SenseCAP S2108 Soil Moisture, Temperature and Pore EC Sensor

Overview
A battery-powered IP66 LoRaWAN wireless sensor that measures soil volumetric water content (VWC), soil temperature, Bulk EC and Pore EC simultaneously. Measurement ranges: VWC 0–100% (m³/m³), temperature -40 to +80 °C, Bulk EC 0–20 mS/cm, Pore EC 0–32 mS/cm. Built-in Bluetooth enables configuration via SenseCraft App and supports OTA firmware updates and remote device management. Designed for precision agriculture, greenhouse monitoring and long-term environmental monitoring.

Key Features

• Global LoRaWAN compatibility with universal frequency plan support (863–928 MHz).
• Battery-operated with replaceable D-size Li-SOCl2 (ER34615) cell; up to 10 years estimated battery life depending on settings.
• IP66 enclosure and wide operating temperature range (-40 to +85 °C) for outdoor deployment.
• 5 m detachable probe cable for flexible installation and easy maintenance.
• Onboard Bluetooth for simple app-based (SenseCraft App) no-code configuration.
• Multi-parameter sensing (VWC, soil temperature, Bulk EC, Pore EC) for comprehensive soil analysis.

Applications

• Irrigation optimization and scheduling in arable farms and orchards.
• Greenhouse climate and substrate monitoring for automated control systems.
• Landscape and turf moisture monitoring for grounds maintenance.
• Integration with smart farming platforms and IoT systems for precision agriculture.
• Long-term environmental, ecosystem and research monitoring.

Technical advantages & connectivity

• LoRaWAN v1.0.3 Class A support with wide channel plan compatibility (IN865/EU868/US915/AU915/AS923/KR920/RU864).
• Built-in Bluetooth for local parameter changes and provisioning via SenseCraft App; supports OTA updates for remote maintenance.
• Optimized low-power radio and long transmission range (typ. 2 km urban / up to 10 km line-of-sight depending on environment and gateway antenna).

Performance guarantee & reliability tests
Device validated through High-Low Temperature, Conformance, Waterproof, Freezing and Long-Range Communication tests as well as R&D and production quality checks to ensure consistent field performance.
