I am an art student and work in an project involving
measuring plants electric reactions to their immediate
Basically I thought of measuring either the galvanic
response (changes in conductivity) or the changes in
potential difference (of plant part and '0').
This measurement is fed into an amplifier (normal
audio stereo amplifier) and responses would be heard
as sound trough the speakers in the room.
What is the best way to measure responses?
Are there any simple (=cheap) devices that would
make this possible?
Any comments, information, pointers, flames, etc.
