MODULAR SENSOR ARCHITECTURE FOR SOIL AND WATER ANALYSIS AT VARIOUS DEPTHS FROM THE SURFACE

Abstract:

A method of analyzing soil using a modular sensor device. The modular sensor device including a sensor bus head, a sensor bus terminus, and a sensor rod in a stacked arrangement. The sensor rod disposed between the sensor bus head and the sensor bus terminus. The method including setting on an output pin of the sensor bus. The method further including, subsequent to setting the output pin of the sensor bus, detecting a transition on an input pin of the sensor rod, the output pin of the sensor bus and the input pin of the sensor rod being part of a daisy chain. The method further including, in response to detecting the transition at the input pin of the sensor rod, enabling bidirectional communication between the sensor rod and the sensor bus head over a communication bus electrically coupling the sensor bus head to the sensor rod.
