Development and implementation of a web application for the management of data recorded by a carbon monoxide sensor

Abstract

The purpose of this work is to develop and implement a web application that can store, analyze and graph the data recorded by a carbon monoxide (CO) sensor. An artificial ventilation system is also proposed to reduce the amount of carbon monoxide concentration by activating fans. In this paper, four levels of carbon monoxide concentration were identified ranging from 20 to 449 parts per million (ppm) which is the normal level. Depending on the level of CO recorded by the sensor, a certain number of fans will be activated. The project is based on the work in [1] where a CO sensor sends data to the web application which then stores it in a database. The user can access the application via any device with access to the internet to be aware in real time of the data recorded by the sensor. The information recorded by the sensor can be detailed through charts and reports; this data includes the date and time of the last dangerous event, the number of registered users, the day of execution of the query and the time when the sensor is connected to the app.
