Description

A simple flex sensor 2.2″ in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol.

The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend).

Connector is 0.1″ spaced and bread board friendly. Check datasheet for full specifications.

Introduction

The Flex Sensor 2.2 Inch is a compact bend sensor used in Arduino projects, robotics systems, wearable electronics, and interactive electronics applications. This sensor changes its electrical resistance when bent, allowing microcontrollers to detect movement and flex angles accurately.
