CSF15Y Soil Moisture Transmitter Time-domain reflection TDR RS485 (Modbus-RTU protocol)
CSF15Y series soil moisture sensor is based on the principle of time-domain reflection TDR, which is a dielectric sensor, which has strong independence, and its results are basically independent of soil type, density and temperature. Therefore, when the moisture content in the soil changes, the dielectric constant of the soil also changes considerably. This series of soil moisture sensor circuits minimizes the effect of temperature changes on the measurement. Digital technology and durable materials enable high measurement accuracy and low price. The sensor enables long-term continuous monitoring of moisture content at multiple plots and at different soil depths.
