Objectives
In the market, optical fiber biosensor needs to use bulky equipments that include tunable laser and spectrum analyzer. The spectrum analyzer cans only analyzer one to two optical fiber biosensor. If we have a lot of sample need to be analyze at the same time. We need to use more equipment that is expensive. The target samples need to be connected physically to the equipments. These wired connection let the testing not flexible enough, when you testing the samples in a lab which use a puter to log and analyze all the samples data at the same time.
In this project, we would want to provide a low cost work for the connection between optical fiber biosensor and puter. It will include three parts.
Wireless module: It include a microcontroller, Analog to Digital converter and RF transmitter
Photo detector: It converts light intensity to electrical signal (Voltage)
Optical biosensor: It will reflect the laser which the intensity will affect by number of biomaterials attachments.

Background
Optical Fiber BioSensor System
Review of Optical Fiber biosensor Theory (Field of study)
The biosensor Fabry-Pérot interferometer
Motivation of using work in optical sensor system
We want to find a low cost, ease of deployment, multi-source sensor and battery operation platform to transfer the data to puter. Using wireless work is one of good solution.
Problem description
Using optical fiber as biosensor has grown popular over the past few years as makers continue to develop new technology.
One of the problems of optical biosensor is that the sensor needs to wire with a mas
