Implementation of a 30*30 cm force sensitive paper sensor with an MCP6002.

The sensor is sandwiched between wooden plates containing the electronics.

The sensor outputs from 5 kOhms when no load applied, down to 1kOhm when 100kg load is applied.

With 5V input and a Rd resistance of 500ohms for the voltage divider it outputs a voltage between

5*Rd/(Rd+Rsmax)=5*500/(500+5000)=0.45

and 5*Rd/(Rd+Rsmin)=5*500/(500+1000)=1,67

The first Op-Amp of the MCP 6002 will be used to triple
