If I use other sensors that default connected to certain places on head and ears. EEG measures current made by brain and transported on skin. Knowing Ohm Law (V = IR) we could in theory calculate voltage. If there is mistake in my text I would be happy to learn something new

for the maximum resolution get the highest number of bits you can find.
You mean it is possible?
According to the schematic, Grove_GSR is a differential amplifier that amplifies the change in skin resistance converted to voltage by a factor of 2ā¦ It is assumed that the change in skin resistance is large (50k-500k).
On the other hand, EEG currents are very weak and buried in noise, so Grove_GSR would not be able to detect them at all.
yes like he saidā¦ i dont think the electrodes used in the grove kit would be suitableā¦ are you just trying to do a science fair project? do you have any knowledge of how eeg work? PJ made a deviceā¦ maybe he may know!
