What is an HPzenAi Agri Soil Sensor?
The HPzenAi AGRI-SOIL-8F is an IoT-enabled multi-parameter soil sensor that simultaneously measures up to 8 soil conditions at root zone depth. Its stainless steel IP68 probe inserts directly into the soil and communicates via RS485 Modbus RTU through the HPzenAi Gateway, delivering real-time soil data to the HPzenAi app for smart irrigation control, fertigation monitoring, and crop health analysis.
8-Parameter Soil Sensing
Measures volumetric moisture, temperature, EC, pH, nitrogen, phosphorus, potassium, and salinity in one probe
IP68 Stainless Steel Probe
Fully waterproof, corrosion-resistant 55 mm probe with 7-pin waterproof connector for permanent field installation
RS485 Modbus RTU
Reliable wired communication to the HPzenAi Gateway for continuous monitoring and cloud data upload
Smart Irrigation Analytics
Real-time soil data, historical trends, irrigation trigger alerts, and fertigation schedules in the HPzenAi app
Product Description
The AGRI-SOIL-8F combines multiple sensing elements in a single compact stainless steel probe, eliminating the need for separate sensors at each monitoring point. It powers from a 12V DC supply and communicates to the HPzenAi Gateway via RS485 Modbus RTU. The 7-pin waterproof connector ensures secure, moisture-proof field connections. Measured data uploads continuously to the HPzenAi cloud for dashboards, alerts, and irrigation automation.

Applications & Use Cases
The AGRI-SOIL-8F is designed for precision agriculture deployments where continuous, multi-parameter soil monitoring drives smarter irrigation, fertilisation, and crop management decisions.
| Application | Description |
|---|---|
| Drip Irrigation Control | Trigger irrigation events automatically when soil moisture falls below target thresholds, preventing under- and over-watering |
| Fertigation Monitoring | Track N-P-K levels in real time to optimise fertiliser application rates and timing, reducing waste and cost |
| Crop Stress Early Warning | Monitor soil temperature and EC at root zone to detect stress conditions before visible symptoms appear |
| Soil Mapping | Deploy multiple sensors across a field to build spatial maps of soil moisture, EC, and pH for variable-rate inputs |
| Greenhouse Production | Continuous substrate monitoring in grow bags, rockwool, or soil beds for high-value horticultural crops |
| Orchard & Vineyard Management | Long-term root-zone monitoring for tree crops and vines where consistent soil conditions drive yield and quality |
| Research & Trial Plots | Accurate, timestamped multi-parameter data for agronomic research, variety trials, and soil amendment studies |
| Water-Use Efficiency Reporting | Log irrigation volumes against soil moisture response to demonstrate water-use efficiency for compliance and audits |
Available Models
The AGRI-SOIL-8F communicates via RS485 Modbus RTU to the HPzenAi Gateway. The 8-parameter probe measures moisture, temperature, EC, pH, N, P, K, and salinity.
