This will allow you to demonstrate the resistive nature of the sensor with a resistor/capacitor discharge time measurement circuit; no correlations to weight are made. The resistance of the Flexiforce sensor is proportional to weight. The sensor included in the kit has a resolution of ≈ 1.6lbs. The active sensing area is a .375" diameter circle at the end of the sensor. The conductive leads are easy to connect to a breadboard or through-hole area. The Flexiforce has an ideal output for A/D conversion - 0V is no force and 4.2V is 25 lbs. The RCTIME command may be used with a LOOKUP table or calibration formula to execute some math to make the output useful.
