When maximum pressure is applied its resistance drops to about 200w. Both the electrically conducting and non conducting particles are present on this sensing film.

When a light pressure is applied to the sensor its resistance drops to about 100kw.

Force sensitive resistor midi. Adafruit industries unique fun diy electronics and kits round force sensitive resistor fsr interlink 402 id. Have it act as a button for switching devices on or off. Force sensitive resistors or fsrs do exactly what their name suggests.

How to measure forcepressure with an fsr as weve said the fsrs resistance changes as more pressure is applied. Force sensitive resistor midi piano velocity. Or do you already have a solution for this.

Analog voltage reading method the easiest way to measure a resistive sensor is to connect one end to power and the other to a pull down resistor to groundthen the point between the fixed pulldown resistor and the variable fsr resistor is connected to the analog input of a microcontroller such as an arduino shown. 166 fsrs are sensors that allow you to detect physical pressure squeezing and weight. There are plenty of uses of a force sensing resistor in arduino projects.

Below is just a few examples of what you can do. You can connect multiple force sensing resistors to the arduino and have them act as inputs. I think that the biggest challenge will be put one fsr per key with the limited number of analogic inputs.

How to add velocity sensitivity aftertouch to piano toy midi controller. Force sensing resistors are variable resistors which change resistance according to the pressure or force applied to them. For example you can use them to play a tune each time to tap the sensor.

They vary the resistance between their 2 pins based upon the force applied the resistance goes down as the force increases. Hence these are termed as fsr sensors force sensing resistor is a combination of resistor and sensor technology. Under no force the resistance is very high pretty much infinite.

The force sensing resistor is generally supplied as a polymer sheet or ink which is applied as screen printing. This sensor is a interlink model 402 fsr with 12 diameter sensing regionfsrs are basically a resistor that changes its resistive value in ohms omega. This graph indicates approximately the resistance of the sensor at different force measurements.

They are simple to use and low cost. Biga june 19 2013 at 1045 am. Fsrs are one of the easiest sensors to use and are found quite frequently in musical instruments.

When there is no pressure the sensor looks like an infinite resistor open circuit as the pressure increases the resistance goes down.
