IOT PROJECT

Identification and Visualization of Hazardous Gases Using IoT

Abstract:
              Air pollution is increasing exponentially because of natural and human causes. Adverse effects of air pollution are not only limited to human beings, flora and fauna but are extended to the historical monuments as well. Thus, air monitoring has become an imperative task for society. Atmospheric Air Surveil System (AASS) comprises of a portable model for the remote web-based monitoring of Carbon Monoxide (CO) and Carbon Dioxide (CO 2 ) gases in outdoor regions. The sensor mote (device) consists of a microcontroller, gas sensors and Global Positioning System (GPS). The calibrated sensor grid is used to measure the concentration of the gases from surrounding which are then processed using the microcontroller. The processed data from the motes are transmitted to the cloud via the Internet of Things (IoT). Using MQTT (Message Queuing Telemetry Transport) protocol these data are fed to the server after which, they are stored in the Data Acquisition (DAQ) unit. The dashboard is provided for the visualization of the stored data. Email notifications, activity log, Geographic Location Verification (GLV) and Device Authentication (DA) functionalities are provided. Also, the authorized user can control the whole device from a remote location. This system is tested for the scalability.
