I’ve just got my Grove GSR sensor, along with a GrovePi+ and a Raspberry Pi. I’m following the process at http://wiki.seeedstudio.com/Grove-GSR_Sensor/, and I’m adjusting the potentiometer until I get a reading of 512. However my sensor values always jump from around 535 down to ~25, no matter how slowly I turn the screw. Is this normal?
I also can’t seem to get any changes in reading when wearing the sensor. It does seem to be somewhat working, as if I touch the electrodes together I get readings near 0.
I’m using the grove_analog_read.py script from the git repo.
Can you provide me with any hints to get it working properly?
