Aquaflex Soil Moisture Sensor (RS485 interface for Modbus)

Truebner Aquaflex (RS485 interface for Modbus) - capacitive soil moisture sensor

The capacitive soil moisture sensor AquaFlex Sensor is used to measure the average soil moisture along a 3 m long special measuring cable.

In contrast to point measuring capacitive soil moisture sensors such as the SMT50 or the SMT100, the moisture is thus measured in a much larger measuring volume.

The AquaFlex sensor is therefore ideal for reliable soil moisture measurement and for easy installation in an existing lawn.

The special measuring cable has a robust polyethylene sheath and is very durable.

Specification of the Truebner Aquaflex capacitive soil moisture sensor:

Soil moisture and temperature sensor, measuring range 0-100% VWC, -20 to +80 degrees Celsius, RS-485 digital interface with Modbus protocol, supply voltage 4...28 VDC, 3 m measuring tape length, 10 m connection cable.
