Soil Moisture

The probe measures the soil volumetric water content by using a capacitive measurement principle which allows fast measurements in the field and with minimal invasiveness. The volumetric content of water is defined as the ratio between the volume occupied by water in a given portion of soil and the total volume. As a result the measurement can be expressed as a percentage of the water volume with respect to the total volume.
The circuit board is protected inside a housing made of plastic material and sealed with epoxy resin which allows to achieve reliable measurements even in harsh environmental conditions.
The probe is supplied with an RS485 digital output and Modbus-RTU protocol. This solution ensures the use of very long connection
cables. The sensor is also supplied with a standard 5m power and signal cable.
