pylon:
A voltage level on one of the analog pins.Not directly but they depend on the skin resistance value if the sensor is applied correctly.
You need to calibrate the sensor. The Grove sensor is not designed to deliver µS values. It's thought to show changes in the skin conductance and not to provide absolute values.
thanks alot for your reply, im sorry for the dumb question but how can i calibrate the sensor to get skin resistance and skin conductance value? sorry im still new to arduino and sensors
i got this equation from a website:
Human Resistance = ((1024+2*Serial_Port_Reading)*10000)/(512-Serial_Port_Reading), unit is ohm, Serial_Port_Reading is the value display on Serial Port(between 0~1023)
should i get the resistance from this equation then convert them to skin conductance (i read conductance is simply the inverse of resistance)
even though i tried this equation and put the SensorValue in place of Serial_Port_Reading, it didnt give values expected for resistance in ohms (from 50k to 10M)
what do i do please?
