As the force varies on the sensor output voltage varies in Analog manner. Other applications include force feedback for the autopilot automatic disconnect function and flap jam detection systems. Other types of force sensors are available. Whether it's critical applications such as IV drips or dialysis, or serious engineering like robotic end-effectors, Honeywell offers a broad line of force sensor options. This circuit is so designed that when no force is applied to the strain gauge, R 1 is equal to R 2 and the resistance of the strain gauge is equal to R 3. Arduino further processes this data and thus determines the frequency with which the buzzer produces sound. The most basic force sensor is a simple force sensitive resistor. PVDF nanofibrous fabrics were prepared by using an electrospinning unit and characterized by means of scanning electron microscopy (SEM), FTIR spectroscopy and x-ray diffraction. Note that our method takes the somewhat linear resistivity but does not provide linear voltage! High force will make the output to read from 9v to 12v maximum ( approximately ). On the other hand another voltage divider pair is formed using Resistor R2 and variable resistor R3. When no pressure is applied, voltage output from the FSR and R1 pair will be low comparing to output voltage of R3 and RV1. It senses the distance from the obstacle and sends this data to Arduino. Calibration is quite important for this circuit to work so perform proper calibration using POT RV1 before using it. These diagrams are essential, especially when several forces are acting on the object simultaneously.
