i am taking gsr value and in some subject it is shown zero during the complete session of measurement (around 5mint) or it some time zero and giving data in the same session of recording. how can i correct this issue/?
Ps: i have calibrated the gsr by making it 512 when its not in touch with skin
Hi there~
Could you please attch the code you use, and a picture to show the hardware connection will be helpful. Thanks

I am getting a similar issue except it never changes from 0. If I use the pot to change the resistance, I can ratchet it up to 45 on the plotter but that’s all.
If I disconnect the sensor and plot the analog values on the pin, I get a return. I plug the sensor back in (after unplugging the board) and the returned value goes back to 0 (or 45 if I left the pot at that position).
I have tried simply reverting to the original Grove-GSR_Sensor tutorial. But it’s still 0.
I have several of these sensors and they were working fine and now they aren’t. They’re for a project and I am struggling to keep my client from becoming impatient.
Is it possible for the sensor to simply stop working?
