Soil Moisture & Temperature & EC Sensor

Soil Moisture, Temperature and EC Sensor

Product Description

This Soil Moisture & Temperature & EC Sensor MODBUS-RTU RS485 (S-Soil MTEC-02A) is designed with industry standards, featuring high precision and high sensitivity and durability. Incorporating three sensors (soil moistures sensor, soil temperature sensor, and soil electrical conductivity) into one, with auto temperature compensation, this sensor ensures the accuracy of measurements regardless of the environment changes.

By measuring the dielectric constant of the soil, it can stably measure the soil VWC (volumetric water content) regardless of various soil types. The measurement conforms to current international standards for soil moisture measurement.

The stainless steel probe can be permanently inserted in the soil with quick testing for long-term use. This soil sensor is IP68 rated, very robust and durable, suitable to be applied at long-term monitoring of soil moisture, temperature and electrical conductivity at scientific experiments, water-saving irrigation, gardening, greenhouses, outdoor farming, horticulture, golf turf management, forestry, precision agriculture, and other professional environmental monitoring scenarios. It can also be applied in the water, nutrient solution, and other kinds of substrates where the EC level is needed.
