Aquaflex Sensors

To allow ease of connection to the multitude of Telemetry Systems, Logging Systems and Irrigation Controllers the Aquaflex Sensor has been made to be compatible with all common interfaces.

See the list below for a solution to connect Aquaflex into your system.

Aquaflex with SDI-12

SDI-12 is a serial communication protocol for sensors. The Aquaflex SDI-12 communication is done in accordance with the SDI-12 Standard, Version 1.3.

Aquaflex with 4-20mA

The Sensor has two separate 4 to 20mA outputs of soil moisture (in volumetric percent), and soil temperature. These outputs facilitate easy connection to dataloggers, irrigation controllers, telemetry systems etc.
These signals may be used separately or simultaneously at any time without any changes to the sensor

Aquaflex with Pulse

The Aquaflex sensor produces two pulse outputs, representing volumetric soil moisture and temperature respectively.
