I need someone who knows about pressure sensor modules programming and bluetooth

I would like help creating a proof of concept with real function. My idea is to use a FSR pad on the resistance pad for an exercise bike. I would need some sort of programmable module that can send via bluetooth a resistance number value of 0-100 (programmed based on force applied) to a cell phone as well as a digital readout display. Size I'm hoping to make it sleek and small so it doesn't interfere with the user of the bike. Attached: you will find a drawing of an exercise bike with the resistance mechanism. the placement of the pad would be between the rubber and the leather pad before the flywheel.
