Mysentech MST Sensor

MST (Mysentech Soil Trio) is a 3-in-1 sensor integrating soil moisture, electrical conductivity, and temperature measurement. Utilizing high-precision digital sensing technology and embedded processing algorithms, it accurately measures soil volumetric water content, electrical conductivity (EC), and temperature. Key features include high sensitivity, precise measurement, stable operation, low power consumption, excellent weather resistance, and ease of use, making it suitable for broad applications in agriculture, forestry, horticulture, and related industries. Each sensor undergoes temperature coefficient calibration and soil moisture accuracy calibration prior to shipment, enabling users to begin data acquisition immediately. These sensors communicate via the RS485 serial bus standard for enhanced noise immunity.
