Note
This Industrial Soil Moisture, Temperature & EC Sensor comes in two versions. The main difference is in the cable connector. Please choose the version that best suits your needs:
(1) S-Soil MTEC-02B: with a waterproof aviation connector. This version saves you time in deployment as you won't have to use screws to connect the cable to the data logger. And it can be used with SenseCAP Sensor Hub 4G Data Logger instantly with ease.
(2) S-Soil MTEC-02A: with hook-up wires.

Soil moisture is the water stored in the soil. Soil temperature is the warmth of the soil. Soil electrical conductivity (EC) is the level of salts in soil (salinity). These parameters are very important indicators of soil fertility and health, which ultimately affect the plants. When there is a high soil salinity, the salt will make it difficult for the plants to consume water even though there is a high moisture level in the soil. This will ultimately "burn" the plants. Meanwhile, too much moisture in the soil is not only bad for the plants but also wastes water and adds extra burdens to our planet earth.
Plants grow best in their preferred environment, at the optimal ranges of soil moisture, temperature, and EC level. It's important for growers to get access to the data of these parameters, to get insights on what actions need to be taken to ensure plant health and higher yield.
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 moisture sensor, soil temperature sensor, and soil electrical conductivity) into one, with auto temperature compensation, this sensor ensures the accuracy of measurements regardless of the environmental 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.
