Thin Film Pressure Sensor

1. Example Code for Arduino-Pressure to Serial Output

We use flex sensor together with Arduino UNO mainboard in this tutorial, and the tutorial will demonstrate how does the serial port output change under different pressure conditions.

Reference

This article explains the principle behind flexible pressure sensors, which use ultra-thin films and nanometre pressure-sensitive layers to convert applied pressure into measurable resistance.
