Development of an Optical Sensor for the Detection of Volatile Organic Compounds

Volatile Organic Compounds (VOCs) are organic compounds with a low boiling point at room temperature. This fact leads to their easy evaporation into the nearby air, intoxicating it and making breathing hard for living species especially human beings are vulnerable to audible and visual damage. Technological advancements in biomedical engineering have led to the development of various methods to moderate this problem. In this paper, we present an optical sensor that can be used to analyze the quantity of VOCs in air. The technique deploys Absorption Spectroscopy based measurements at different points in a defined area. Emphasis has been led to the optical setup that uses a mechanical chopper and a set of lenses, since the main results rely heavily on it. Some of the important outcomes are presented and discussed in detail which leads to attention grabbing graphical results.
