I-CubeX Forum

I have a flex sensor with a resistance value between 10 and 40K Ohms. Two leads. How do I wire it to the Icube box?

I tried wiring it:

Power to first flex sensor lead. Second flex sensor lead to signal, signal to ground.

I got 127 and it didn't move. I assume it's because the resistance value is too high.

Hi,

You need to make a voltage divider circuit with your flex sensor. You will need a resistor of about 47k that you will install between POWER and SIGNAL then your flex sensor between SIGNAL and GROUND. This way the voltage will change at the SIGNAL input when you bend the sensor.

Regards.
