Soil Temperature: The sensor is equipped with a digital temperature sensing chip on a probe, which uses copper-clad method to increase the temperature transmission efficiency, which is used to measure the temperature of the probe surface, that is, the soil.
Soil Volumetric Water Content: The sensor uses the FDR principle based on the dielectric constant, which has been used to measure the influence of the soil dielectric constant on the transmission of high-frequency signals in order to calculate the soil volume rate in reverse.
Soil Electrical Conductivity (EC): The sensor measures the error by applying alternating current on two metal probe points to calculate the soil conductivity. The alternating current method avoids the bias effect caused by the unidirectional voltage, and at the same time the conductivity measurement is added and the temperature self-correction is added.
The sensor adopts automatic sleep setting and works every 5 minutes. The data change cycle is 5 minutes.
Power supply voltage: DC6-24V
Instantaneous current: ≤15mA average current＜3mA
