School Project – Logarithmic Conductivity Tester
1,2,3, or 4 LEDs light up if the conductivity between P1/P2 is greater than 1uS, 10uS, 100uS or 1mS, respectively.
Test conductivity of your skin, apples, rain-water etc. Due to the logarithmic feature a large range is covered. Each LED indicates 10-times better conductivity that it’s neighbour.
The downloadable file contains the complete KiCAD project.
