A Simple Wenner Array (Project 0039): Difference between revisions

This project is a Wenner Array, a device designed to find the resistivity of soil. It is comprised of a set of 4 equidistant electrodes, the outer two sending a small current between each other, and the inner two measuring the voltage difference between each other. This can be used to analyze the water content of soil, or to detect hidden objects under the ground. This micro Wenner Array has 13.33 mm between terminals, rather than the meters for a regular Wenner Array, but you can extend the same principles to a larger array. This Wenner Array was designed to measure up to 1 Mohm across the voltage terminals, or 84 kOhm meters. This array has 4 components:
