FPGA Implementation of contactless position sensor using FSR (Force sensing Resistor)

This paper presents a contactless reprogrammable position measurement system designed using the HDL(hardware description language) and realized in hardware using the field programmable array (FPGA). The proposed system is able to measure the contactless position at various locations with each of them to its accuracy. It is used to measure pressure and motioning purposes using magnetic principles. In addition, the proposed system incorporates feature that measure position at contactless in real time. This system effectively detects the linear displacement in terms or resistive variations using Force pressure sensors (FSR). The proposed system uses a reprogrammable controller (FPGA), as it is possible to customize the design to various industry applications.
