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 ...

I feel I learned a lot about how to refine my thoughts. 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 ...

Use the Arduino IDE to upload the Arduino sketch located in the /GSR-Sensor/GSR-Sensor.ino directory. Now you're ready to measure human resistance using the GSR ...

In this particular case, it’s a DIY USB polygraph-like machine by [Juangg] using an Arduino and sensors on ... complete with 3D printed enclosure and sensor elements. The polygraph may have ...
