I would like to measure a plant's electric activity / voltage, I've looked online to find out where to place the electrodes and what type of electrodes to use but they seem to very wildly. Any ideas?
At the moment
- I plan on wiring one end of a needle to the stalk and one end to the soil.
- The connections from the plant would go to a laptop mic input to record the signal then I would normalize the signal.
- I would then process the signal in MATLAB/Octave using FFT.
Any thoughts or videos on connecting the electrodes to the plants or trees?
