Calibration: Adjust RV1 to calibrate the sensor for accurate readings.; Electrode Placement: Place the electrodes on the skin.; Power Up: Power the circuit and observe the output signal on the ...

For a proof of concept, I created a rough circuit of the GSR sensor frontend for interfacing with an Arduino microcontroller. This does seem to work but LM358 is not a rail-to-rail output op-amp. So, ...

This section explains the design and functioning of the GSR sensor circuit, which measures the electrical conductance of the skin. The conductance varies with the moisture level and is used to assess ...
