1 Force Sensing Potentiometer (FSP) Overview

This guide covers Ohmite’s standard Force Sensing Potentiometer offerings FSP01CE, FSP02CE and FSP03CE. These
sensors operate as both position and force sensors offering users the ability to control menu navigation, device
function, movement, audio control and many other HMI interaction in a more reliable and intuitive manner. Adding
additional opportunities for user interaction, haptic control lighting, and integration methods.

Interfacing to an FSP sensor is simple and can be achieved using a number of different methods either with a
dedicated microcontroller outputting serial data to a host controller, or directly linked to the host with a few simple
external passive components.

This guide provides all the necessary technical information for the successful integration of Ohmite’s force sensing
potentiometers into products such as:

• Media controllers

• Computer and peripherals

• E-readers

• Industrial, scientific or medical devices

• Home automation and lighting control

• Midi controllers

• White goods

• IOT devices
