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.
