• Measure the speed of data services and also act as WiFi repeater that can act as public WiFi through which various IoT devices can be connected
• The proposed system can predict future behavior and also have an algorithm for fault diagnostics by data modelling and machine learning algorithm
• The system is self-powered by solar power
• It has power management and power saving algorithm
• Create an ideal smart device for smart city

Novelty

• Integrated Air Pollution, Noise Pollution, Data Speed Measurement
• Powerful fault diagnostics and ML algorithm
• Low cost
• It can either act as WiFi repeater or WiFi provider (public WiFi)
• It can also control street lighting and for smart garbage to transmit level
• Power saving algorithm and efficient power usage management
• Gives the use the accurate AQI values through the mobile application
• Sends reports of the status of tier locality at regular intervals

How it Works

This device can be placed at an open environment either on top of buildings or on the top of street lighting. It consists of 4 major measuring units: 
 Air pollution
 Noise pollution
 Miscellaneous ( temperature, pressure, humidity, luminescence)
 Data speed (internet speed)

Air pollution monitoring

The proposed system consists of DC fan which sucks the environment mental air. The sensors are embedded on the duct from which the air pollution is measured. 
The parameters measured are Co2, Co, NH3, O2, S04, O3, NOX, PM 2.5, PM10, smoke. 
The system also measures humidity, temperature and air pressure, the act as determining factor from the measured data the AQI values are derived and calculated.
The noise is measured by a microphone and the analog values are converted to corresponding dB values.
The data speed is measured by the latency of the data packet as the bandwidth is constant. The latency is measured by pinging the web and response time is measured which is proportional to the speed of the internet service. 
The system is enabled with the GPS location so that data from each system is differentiated. It also enables the user to see each area's pollution level.

Web server and analysis

We take data’s from the IoT devices and analyze it visually etc. We put them in ML algorithms and predict the data that might occur in the near future so it will tell us about the pollution that might happen and also the fault occurred or future faults . We do this with the help of cloud platforms.

User interface

The user interface can be either as the Web page or the mobile application
• Graphical and data representation of the parameters are shown and the AQI values are given
• The other parameters are also represented
• The user can see the data of the area where the device is located

This helps in the planning of greenery and optimizes the pollution causing agents, and to study and map pollution which will create an impact.

 

Inspiration

It is well known that the modern world needs technology to make it a better place from what it is now. We as engineers have to build the best possible solution to the problems that we face in our day to day lives to reduce the ill effects caused by our human society on our environment. The IoT technologies are the best possible solution to our problems right now since they can actually react with the environment. India in recent years has seen a great rise in the industrial sectors and automotive industries which has had an undesirable impact in our lives with the day to day rise in noise and air pollutions. This has to curbed and mended since the technological revolution isn't going to slow down any time soon. Keysight being the leading innovators and best solution givers have provided us with a platform to save our environment. They are well versed with the telecommunications, aerospace/defense, industrial, computer, and semiconductor industries can help us achieve our dream of cleaner earth. We as engineers can provide solutions to these problems by making smarter IoT devices which can have significant contributions towards a cleaner environment which is sure to enhance the peoples' life. It is our responsibility to give a better world to our future generations. If there is a future, it has to be green.
