AIR MONITORING SYSTEM USING WIRELESS SENSOR NETWORK

Air pollution is a major environmental issue that can risk human health such as
high mortality rates, cancer, and cardiovascular disease. That is why air pollution is
one of the hot topics for researcher to work on in a project. One of the topics would be
an Air Quality Monitoring. In Malaysia, the existing air quality monitoring station
requires a lot of money and effort to operate due to its immobility. Moreover, these
stations consume a lot of money to install and only the trained staff can operate and do
a maintenance for the system. This project will introduce a popular technology for
monitoring the air quality especially in Malaysia which is Air Quality Monitoring
system using Wireless Sensor Network (WSN). WSN is a technology that allows
multiple station nodes communicate with each other by having the same frequency
band and the collected data can be stored directly in cloud. The sensors that are being
used in this project are MQ-7 to detect carbon monoxide (CO), SEN 0219 to detect
carbon dioxide (CO2), Sharp GP2Y1010AUF to detect particulate matter that are
smaller than 2.5 microns (PM2.5) and DHT 22 to detect the surrounding temperature
and humidity. Communication modules also is needed for implemented WSN such as
Lora module and ESP8266 Wi-Fi module.
