Grove - GSR sensor (SKU: 101020052)

Q1: How to calculate the human resistance?
A1: **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)

Q2: What is the unit of output?
A2:  We measure the signal by voltage and print to COM port as (0~1023). 

Q3: Where can I find technical support if I have some other issue.
A3: Please send an email to
