Does anyone know how to connect grove GSR sensor to Arduino uno directly without using grove board shield?
I bought the sensor from seed studio.
Looks like the finger cot things go in the two connector in the corner.
The four connector is Gnd, VCC, NC, and SIG.
Gnd and VCC are easy.
One of those other two will give an analog output (varying voltage) based on the sensor. I assume is it SIG. Hook it to an Arduino pin and do an analogRead().
Edit: Looks like the NC pin is not used on a number of their sensors, so you are probably good with voltage, ground and signal.
