Decreasing FSR Sensitivty

Projects General Guidance
1

Hello, I'm currently designing a circuit using 2 FSR's to measure foot pressure, however I find they are far too sensitive for the weight ranges given, I was wondering if there is any way to decrease the sensitivy of the FSR by rewiring it in some way.

Attached is my current circuit design, and I have tried replacing the 10K resistors with 22K and 47K to decrease sensitivty, however it seemingly has done the opposite.

Any help would be great.

Find a tutorial on voltage dividers. That will show how to determine the FSR output voltage in terms of load resistor value and FSR resistance (force).

You can get a different unit or possible install stronger springs. Here is a voltage divider calculator for you. Voltage Divider Calculator
