Key features
- 3 sensors in one: soil moisture, temperature and electrical conductivity (EC, salinity)
- Volumetric water content (VWC) measured via the dielectric constant, stable across different soil types
- Built-in automatic temperature compensation
- RS485 output with Modbus-RTU protocol
- Wide 3.6–30 V DC supply range
- Anti-corrosion electrodes and black flame-retardant epoxy resin sealing, IP68: can stay buried or immersed in soil, water, nutrient solution and other substrates for a long time
- EC measurement also in water and nutrient solutions
- Version with waterproof aviation connector, compatible with the SenseCAP Sensor Hub 4G data logger
