SE02-LB LoRaWAN Soil Moisture & EC Sensor

The Dragino SE02-LB is a LoRaWAN® soil sensor designed for smart agriculture applications to measure soil moisture, soil temperature, and soil electrical conductivity (EC). It uses FDR (Frequency Domain Reflectometry) technology with temperature and EC compensation to ensure accurate measurements in saline-alkali and loamy soils. Factory-calibrated for mineral soil, the sensor transmits reliable soil data over long-range LoRaWAN networks with ultra-low power consumption.
