Soil Moisture & Temperature Sensor
Dual-function soil sensor for accurate moisture and temperature monitoring. Built for permanent installation and continuous data logging in agriculture and environmental applications.
Product Description
This soil moisture and temperature sensor combines two essential soil monitoring functions into one durable, stainless steel probe. Designed for insertion into the soil surface or profile, it provides fast and accurate readings ideal for precision agriculture, irrigation systems, and environmental monitoring.
Moisture measurement is based on the FDR (Frequency Domain Reflectometry) principle, using changes in the soil's dielectric constant to calculate volumetric water content. The temperature sensor uses a precision platinum resistance element to ensure highly accurate thermal readings. The unit includes built-in drift calibration and temperature compensation circuitry to maintain reliable performance in changing field conditions.
This sensor is suitable for long-term, permanent underground installation and is compatible with most data loggers and monitoring systems. It’s a dependable tool for researchers, growers, and environmental professionals who need consistent, real-time insights into soil conditions.
