Flexiforce Pressure Sensor Arduino Code
Has anyone had any success hooking up the flexiforce 100lb pressure sensor to the arduino.
Flexiforce pressure sensor arduino code. 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. 9 53 mm dia 0 375 in 0 g 0 lb 45 36 kg 100 lb shape and size. When a force is applied to the sensor this resistance decreases. Use this url to share.
This example uses the 25lb version but the concepts learned apply to all the flex sensors. We hooked up the the left pin to the 5v the middle pin to ground and the right pin to a0. The circuit for this arduino project is super easy as we only need the force sensing resistor and a 100k. The code is very simple consists of a few lines.
When the force sensor is unloaded its resistance is very high. This is what we have done. An fsr force sensitive resistor is a sensor that allows you to measure physical pressure weight and squeezing. The flexiforce single element force sensor acts as a force sensing resistor in an electrical circuit.
It is pretty advanced and will measure the approximate newton force measured by the fsr. Pull down resistor and the sensor is read on analog 0 pin. Flexiforce sensor arduino programming. In depth code for analog fsr measurements this arduino sketch that assumes you have the fsr wired up as above with a 10k.
For the flexiforce sensor interfacing watch my video tutorial available at the end. Plus example circuits and arduino code to get you started. Arduino uno or other arduino compatible board flexiforce pressure sensor breadboard m m jumper wires 1 megaohm. The same program will also run on the arduino mega arduino pro mini and arduino micro.
Force sensor resistor pressure pad 100k resistor. This is the only setup that gives us a reading. Introduction this is a quick how to explaining everything you need to get started using your flexiforce pressure sensor. Share on google share on tumblr submit to reddi.
Below is the full list of equipment that you will need to complete this arduino pressure pad tutorial. The force sensitive resistor or fsr is connected with the analog pin a0 of the arduino. Requirements necessary hardware to follow this guide. The resistance can be read by connecting a multimeter to the outer.
