RS485 Soil Moisture & Temperature & EC Sensor
Introduction
Moisture / Temperature / EC all in one
High reliability and stability
Universal protocols: MODBUS RS-485
Wide range power supply: 3.6V ~ 30V
IP68 rated, suitable for long-term applications
Can be used in soil, water, nutrient solution, and other substrates
Strong Anti-interference: made of ame-retardant epoxy resin
Anti-corrosion, with excellent performance for long-term use
Easy to use, integrate and install
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 scientic
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 EC level is needed.
