【SM150 Soil Moisture Sensor Product Introduction (English Version)】
The SM150 Soil Moisture Sensor, developed by UK-based Delta-T Devices Ltd., is a high-performance measurement tool designed for agricultural management, environmental monitoring, and scientific research applications. Utilizing Time Domain Reflectometry (TDR) technology, this sensor accurately determines volumetric water content by measuring the propagation time of electromagnetic waves along its probe rods, delivering reliable data for irrigation optimization and soil analysis.
Featuring a robust construction with stainless steel probes and weather-resistant polycarbonate housing, the sensor ensures long-term durability in field conditions. The 15cm probe length provides representative measurements across different soil layers while minimizing soil texture interference. Integrated temperature compensation enhances measurement stability across a broad operational range from -20°C to +50°C, maintaining accuracy in varying climatic conditions.
Engineered for easy deployment and continuous monitoring, the SM150 supports both portable handheld readers and automated datalogging systems. Its low-power consumption design makes it ideal for solar-powered monitoring stations, with IP68-rated waterproof construction ensuring reliable performance in heavy rainfall or irrigation environments. The probe s specialized surface treatment resists chemical corrosion and mineral deposits, enabling consistent measurements even in saline soils.
This sensor finds extensive application in precision agriculture for irrigation scheduling, greenhouse climate control, ecological restoration projects, and hydrological studies. Compatibility with Delta-T s software suite allows networked monitoring of multiple sensors, enabling comprehensive data analysis through intuitive visualization tools. Offering both analog and digital output options, the SM150 seamlessly integrates with various data acquisition systems, providing flexible solutions for diverse monitoring requirements. Its maintenance-free design and stable calibration ensure years of service with minimal operational intervention.
