HM-S485 Industrial Soil Moisture Sensor | RS485 Modbus Output | 0-100% VWC | Rapid <0.5s Response | High Accuracy ±3% | for Irrigation Systems, Agriculture, Greenhouses

The HM-S485 enables growers to precisely monitor soil moisture in real-time for optimized irrigation and maximum yields. Using innovative capacitive sensing technology, the industrial-grade HM-S485 accurately measures volumetric water content from 0-100% across all soil types, with rapid sub-0.5 second response times. With accuracy within ±3% in the critical 0-53% VWC range, integrated temperature compensation, and durable stainless steel probes sealed in epoxy, the HM-S485 delivers stable, precise moisture data even when buried for the long term. The sensor’s Modbus connectivity over RS485 allows seamless integration into new or existing irrigation systems and controllers. With low 10mA average power consumption, the HM-S485 also operates wirelessly for flexible installation. By providing growers with rapid, accurate real-time soil moisture data down to the root zone, the HM-S485 enables data-driven irrigation decisions for optimizing water usage, maximizing crop quality and yields, and improving profitability.

• ✅The HM-S485 provides highly accurate real-time measurements of soil volumetric water content from 0-100%, with industry-leading accuracy within ±3% for the critical 0-53% VWC range. This level of precision enables users to closely monitor moisture levels and make data-driven irrigation decisions for optimal plant health and water usage efficiency.
• ✅With its fast sub-0.5 second response time, users can monitor rapid changes in soil moisture in near real-time. The rapid data refresh allows growers to understand how irrigation events and environmental factors impact moisture levels across the soil profile.
• ✅The industrial-grade RS485 Modbus output provides seamless integration into new or existing automation systems, greenhouses, irrigation controllers, and other equipment with Modbus connectivity. Users can create customized monitoring and control solutions.
• ✅Integrated temperature compensation with ±0.5°C accuracy accounts for the effect of temperature on moisture measurements. This produces true volumetric water content readings that isolate the influence of moisture alone on the dielectric constant.
• ✅As an industrial soil moisture probe built for agricultural and landscaping applications, the HM-S485 is a cost-effective tool for optimizing irrigation to maximize crop yields, reduce water usage, and improve profitability through precision data.
