An FPGA Based Multi-Sensor Atmospheric Testing Device for Confined Spaces

Abstract

Monitoring and maintaining the air quality in confined spaces have become crucial in recent years due to various reasons. This paper presents the design and implementation of an atmospheric testing device for confined spaces using FPGAs. Specifically, the device connects multiple gas sensors such as oxygen, methane, and nitrogen dioxide to an FPGA architecture that outputs a warning signal to the user in the field. Field usage warnings include a camera for image capturing, a buzzer for audio feedback, an LED for visual feedback, and a display for the gas level in the space. The device also outputs to Matlab for graphing to illustrate the accuracy of the sensors. The project seeks to design, simulate, and implement an expandable device that monitors different gases within a confined space with various safety levels and respective warning systems.
