Capacitive Liquid Detection
With the help of Arduino
Some time ago Elektor published my siphonic rain gauge with no moving parts, in which the water that passes when a little siphon empties is detected by short-circuiting two electrodes. At the same moment, articles were in preparation showing that capacitive detection would have a decisive impact. Here I investigate if the “approaches” can be joined.
