Problem statement:

Display a numeric index of the air quality in the area on a mobile phone and help the user identify

highly polluted areas on the map based on the index. Utilizing IOT to upload the data collected by user

to a central server and share with other users. Trace the least polluted routes on map for commuting

convenience. Also works as a stand-alone fire alarm at home.

Components used:

Arduino UNO, HC-05 Bluetooth module, MQ-135 Air quality sensor, Android phone (with GPS)

Software:

Arduino IDE, Android Studio, Javascript

Plan of action:

Hardware implementation

1 Ideation & collection of components.

August 2015

2 Interfacing HC-05 & MQ-135 with Arduino

September 2015

3 Calibrate sensor and fix algorithm for index calculation

October 2015

Android app development

4 Android app for Bluetooth communication

November 2015

5 Use mobile GPS & label map with pollution indices

February 2016

6 Trace least polluted routes on map March 2016

Future scope:

Hardware may be optimized and android app uploaded to market the product, which can help the

people in highly polluted areas to stay healthy .Safety at home can be ensured with the fire alarm

feature.
