Page 4: Fsp01Ce/Fsp02Ce Introduction
Force-Sensing Resistor (FSR) construction can generally be categorized into two types, Shunt Mode or Thru Mode*. These alternate types exhibit different Force vs. Resistance characteristics. Ohmite's FSP01CE and FSP02CE are based on Thru mode sensor construction which has solid top and bottom electrodes both over-printed with an FSR layer. - Page 5 • Take an ADC measurement, A , from pin VW WIPER_2 IPER • Take an average of A and A to get an estimate for the force WIPER_1 WIPER_2 WIPER_1 WIPER_2 Ohmite FSP Series Integration Guide: Force Sensing Potentiometer v1.0 Mar 2018...
