Decagon Echo2 EC20 Soil Moisture Probe

The Echo2 soil moisture probe is a capacitance type sensor which measures the dielectric constant of the soil in order to find its volumetric water content. It does this by calculating the rate of change of voltage applied to the sensor once it is buried in the soil. It is the only one of its kind to have a relatively low sensitivity to saline and temperature effects in the soil.

The Echo2 soil moisture probes have an exceptionally low power requirement making it ideal for use in conjunction with all types of Adcon RTUs. The output signal of the probe is directly related to the input voltage; it requires a voltage stabilizer interface when used with an Adcon RTU. These interfaces can handle up to three Echo2 probes.
