Abstract
Abstract: In this project, we are going to measure the force applied by a headphone on a human ear. For this, we are using FSR (Force Sensitive Resistor) to measure the force. The FSR is interfaced with Arduino Uno for the required purpose along with a 10 km ohm resistor (pull down resistor). The resistance offered is a sum of two resistances means FSR resistance + pull down resistor's resistance which fluctuates between 100 Kohm to 10 Kohm . Also a LCD display connected with a variable 10 Kohm resistor is used to display the force value in Newton. We have taken 2 readings of each different headset one is the maximum value observed and second is the minimum value observed. A mean is taken of these two values and an overall mean of all values of different headsets is taken. Hence the value got, is an average suitable value that a headphone should apply on human ears so that they can be worn for a longer period of time. (approx 4 to 5 hours) Keywords: Force Resistive Sensors, Arduino Nano, Force Measurement.
