Industial Wireless Soil Moisture Sensor

Industrial Wireless Soil Moisture & Temp Sensor – Matric Potential Monitoring

SKU: MNS2-4-IN-WS-WM-L05
$873.00Price
Measure soil moisture tension and temperature in real time. Ideal for irrigation control, agriculture, and soil health management.

  • Product Description

    The ALTA® Wireless Soil Moisture Sensor is a high-accuracy device that measures soil water tension (matric potential) and soil temperature, helping you optimize irrigation, improve crop yields, and monitor soil health. Unlike basic volumetric sensors, this sensor reports matric potential in centibars (kPa)—a more reliable indicator of water availability to plants.

    Designed for precision agriculture, landscaping, and environmental monitoring, it features a wireless design for easy deployment in fields, greenhouses, and research settings. With configurable thresholds, you’ll receive alerts when soil moisture or temperature exceeds your set conditions, enabling proactive response and data-driven decisions.

    ⚠️ Note: Requires a compatible Monnit gateway and may require software. Visit our Gateway & Software section or explore complete sensor kits.

    Key Features:

    • Reports matric potential (soil water tension) for accurate water availability

    • Moisture range: 0 to 240 centibar (kPa)

    • Moisture resolution: ~0.3 centibar (kPa)

    • Temperature accuracy: ±1.0°C (1.8°F)

    • Temperature resolution: 0.1°C

    • Wireless monitoring with long battery life

    • Customizable thresholds for alerts and condition-based monitoring

    Common Applications:

    • Irrigation scheduling in agriculture and vineyards

    • Soil moisture monitoring in landscaping and turf management

    • Greenhouse and nursery growing conditions

    • Soil research and field trials

    • Drought management and environmental studies
