Flexiforce Pressure Sensor Arduino Code

Introduction this is a quick how to explaining everything you need to get started using your flexiforce pressure sensor.

Flexiforce pressure sensor arduino code.

Arduino uno or other arduino compatible board flexiforce pressure sensor breadboard m m jumper wires 1 megaohm. Has anyone had any success hooking up the flexiforce 100lb pressure sensor to the arduino. Requirements necessary hardware to follow this guide. Share on google share on tumblr submit to reddi.

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. The same program will also run on the arduino mega arduino pro mini and arduino micro. This is the only setup that gives us a reading.

Force sensing resistor circuit. In depth code for analog fsr measurements this arduino sketch that assumes you have the fsr wired up as above with a 10k. The resistance can be read by connecting a multimeter to the outer. This example uses the 25lb version but the concepts learned apply to all the flex sensors.

When the force sensor is unloaded its resistance is very high. In this instructable i ll show you how to interface an fsr to arduino and change the brightness of an led depending on the pressure applied on the fsr. Flexiforce pressure sensor 100lbs. They are pretty much used in diy electronics as they are available at low cost.

9 53 mm dia 0 375 in 0 g 0 lb 45 36 kg 100 lb shape and size. This is what we have done. Below is the full list of equipment that you will need to complete this arduino pressure pad tutorial. An fsr force sensitive resistor is a sensor that allows you to measure physical pressure weight and squeezing.

Force sensor resistor pressure pad 100k resistor. The circuit for this arduino project is super easy as we only need the force sensing resistor and a 100k. Flexiforce sensor arduino programming. Plus example circuits and arduino code to get you started.

It is pretty advanced and will measure the approximate newton force measured by the fsr. When a force is applied to the sensor this resistance decreases. Pull down resistor and the sensor is read on analog 0 pin. For the flexiforce sensor interfacing watch my video tutorial available at the end.
