Flexiforce Pressure Sensor Arduino Code

In depth code for analog fsr measurements this arduino sketch that assumes you have the fsr wired up as above with a 10k.

Flexiforce pressure sensor arduino code.

The resistance can be read by connecting a multimeter to the outer. The code is very simple consists of a few lines. This example uses the 25lb version but the concepts learned apply to all the flex sensors. Requirements necessary hardware to follow this guide.

Arduino uno or other arduino compatible board flexiforce pressure sensor breadboard m m jumper wires 1 megaohm. An fsr force sensitive resistor is a sensor that allows you to measure physical pressure weight and squeezing. Below is the full list of equipment that you will need to complete this arduino pressure pad tutorial. When a force is applied to the sensor this resistance decreases.

Force sensing resistor circuit. The flexiforce single element force sensor acts as a force sensing resistor in an electrical circuit. This is the only setup that gives us a reading. Pull down resistor and the sensor is read on analog 0 pin.

The force sensitive resistor or fsr is connected with the analog pin a0 of the arduino. We hooked up the the left pin to the 5v the middle pin to ground and the right pin to a0. Force sensor resistor pressure pad 100k resistor. It is pretty advanced and will measure the approximate newton force measured by the fsr.

This is what we have done. For the flexiforce sensor interfacing watch my video tutorial available at the end. Introduction this is a quick how to explaining everything you need to get started using your flexiforce pressure sensor. Flexiforce sensor arduino programming.

Use this url to share. When the force sensor is unloaded its resistance is very high. The circuit for this arduino project is super easy as we only need the force sensing resistor and a 100k. Share on google share on tumblr submit to reddi.

9 53 mm dia 0 375 in 0 g 0 lb 45 36 kg 100 lb shape and size. They are pretty much used in diy electronics as they are available at low cost. Flexiforce pressure sensor 100lbs. The same program will also run on the arduino mega arduino pro mini and arduino micro.
