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.

Flexiforce pressure sensor arduino code.

Below is the full list of equipment that you will need to complete this arduino pressure pad tutorial. 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. 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. Flexiforce sensor arduino programming. It is pretty advanced and will measure the approximate newton force measured by the fsr.

Use this url to share. Force sensor resistor pressure pad 100k resistor. Introduction this is a quick how to explaining everything you need to get started using your flexiforce pressure sensor. This is what we have done.

Requirements necessary hardware to follow this guide. Flexiforce pressure sensor 100lbs. This is the only setup that gives us a reading. Has anyone had any success hooking up the flexiforce 100lb pressure sensor to the arduino.

For the flexiforce sensor interfacing watch my video tutorial available at the end. Plus example circuits and arduino code to get you started. The code is very simple consists of a few lines. The force sensitive resistor or fsr is connected with the analog pin a0 of the arduino.

When the force sensor is unloaded its resistance is very high. An fsr force sensitive resistor is a sensor that allows you to measure physical pressure weight and squeezing. Pull down resistor and the sensor is read on analog 0 pin. The flexiforce single element force sensor acts as a force sensing resistor in an electrical circuit.

When a force is applied to the sensor this resistance decreases. Share on google share on tumblr submit to reddi. The resistance can be read by connecting a multimeter to the outer. Force sensing resistor circuit.
