Wireless LoRaWAN sensor for precision substrate monitoring in controlled environment agriculture. SenseCAP S-2108 measures volumetric water content (VWC), temperature, and electrical conductivity (bulk EC and pore water EC) in real-time. Compatible with all growing substrates including rockwool, coco coir, peat mixes, and soil. Battery-powered with Bluetooth configuration and long-range LoRaWAN connectivity for greenhouse and field applications.
Multi-Parameter Substrate Monitoring
The S-2108 simultaneously measures three critical parameters for irrigation and fertigation management. Volumetric water content (VWC) indicates substrate moisture levels, temperature affects nutrient uptake and root health, and electrical conductivity (EC) reflects nutrient concentration. The sensor calculates pore water EC (pwEC) using the Hilhorst method, providing accurate nutrient availability data across different substrate types.
Key Features
- Measures VWC, temperature, and EC simultaneously
- VWC range: 0-100% (m³/m³)
- Temperature range: -40 to 80°C (-40 to 176°F)
- EC range: 0-20 dS/m (bulk EC and estimated pwEC)
- LoRaWAN wireless connectivity (2km urban, 10km line-of-sight)
- Built-in Bluetooth for OTA configuration
- Battery-powered for easy deployment
- Compatible with all substrates (rockwool, coco, peat, soil)
- IP66 weatherproof rating for outdoor use
Pore Water EC Calculation
The sensor measures bulk EC and calculates pore water EC (pwEC) using the Hilhorst method. Pore water EC represents the actual nutrient concentration available to plant roots, accounting for substrate moisture content. This allows precise fertigation management across different substrate types and moisture levels, optimizing nutrient delivery while reducing waste.
LoRaWAN Connectivity
Long-range wireless transmission enables sensor deployment across large greenhouse operations and outdoor fields without complex wiring. Compatible with worldwide LoRaWAN networks. Ultra-low power consumption extends battery life while maintaining reliable data transmission. Built-in Bluetooth allows configuration and firmware updates via the SenseCAP Mate mobile app.
Application
Ideal for commercial greenhouse production, controlled environment agriculture, precision field farming, and research applications. Monitor substrate conditions in real-time to optimize irrigation schedules, adjust fertigation programs, prevent over-watering or nutrient deficiencies, and improve crop uniformity. Suitable for tomatoes, cucumbers, peppers, berries, cannabis, ornamentals, and other high-value crops.
