Water is the most import resource, it connects every aspect of our life. Without which we can not survive. But, due to increased population, deforestation, industrialization the water sources are depleting. Today, 1 in 9 people lack access to safe water.

OUR SOLUTION

The proposed solution is a self-sufficient system which combines monitoring (gathering live data and analysis of the data) and alerting systems. The physical setup will move through different locations collecting the data. The data is then analyzed to find the water quality index. If any of the parameters are above the standard threshold an intimation is sent to the officials for quick action. This can prevent contaminated water reaching the consumers and the data gathered can be utilized for further development. With our solution, we aim for the safe, reliable supply of water for the betterment of mankind.

OUR DESIGN

The innovative conceptual design of an Amphibious vehicle i.e, which can run on water and land.

Three wheeler cart inspired design with a base designed in the shape of a boat, to provide the correct buoyancy in which the rear turbine is used to propel the water and act as a wheel.

Front wheels also act as flaps to direct the system in water, which is controlled by a single servo motor.

A novel design of a radar type obstacle detector system based on IR sensor where the sensor is rotated in 360 degrees via transmission and gear system from the dc motor to reduce the use of additional servo's and save battery power. This mechanism is used to avoid collisions and protect the build from damage.

The whole build is made unsinkable by a waterproof transparent covering. Additional covering for electronics is done for safety.

The design can be fabricated with ease using additive manufacturing techniques.

WORKING

The system is an effective IOT based machine learning system which will monitor the quality of drinking water in real time and measures the critical parameters like temperature, pH, turbidity, and dissolved oxygen.

It is an autonomous waypoint based vehicle system. The GPS coordinates for the vehicles are present which can be modified in future online.

It is a self-sufficient system; the required power is generated via solar panel and that is used to charge the Li-ion battery via a maximum power point tracking system (Mppts) which increases the efficiency of charging the battery.

The water vehicle will move through different locations in the waterway measuring the data from the sensors. It has onboard obstacle avoidance system based on an IR sensor which is an additional feature for the safety of the system. The IR sensor is rotated in 360 degrees via transmission rod, a potentiometer is used for the measurement of angle at which the IR sensor is rotated.

If an obstacle is detected the water vehicle changes its course to avoid it and then continues the operation to measure the parameters.

The measured values from the sensors are processed by the controller along with GPS coordinates. These values are then stored in the server via GSM module.

The ML algorithm will monitor the real-time data received from the water vehicle. If any of the parameters does exceed the threshold, an alert is sent to the officials along with the GPS coordinates. The hardware is integrated into the Web application. The Main page will visualize the water purity parameters. An additional progress bar that will change the color and tell the user whether that parameter numerical value is appropriate or not.

ELECTRONIC COMPONENTS AND POWER CONSUMPTION

Components-Arduino nano, Dc motor, motor driver, 180-degree servo motor Ir sensor, Potentiometer, Water temperature sensor. Turbidity sensor, PH sensor, Do sensor. Gsm+Gps tracker, custom Mppts system build using bc107 transistors, capacitors and resistors and relay.

These are the electronic components which consume power. With experimenting and online datasheets, we have calculated the power consumption of each component and combined the system power consumption is 12.06 Watt while in motion and 3.075 Watt when stalled.

The 12v solar panel is used to continuously supply the power in daylight is selected. The Li-ion battery which is triple the required capacity is used in the build.

This cycle of charge and discharge is provided throughout the year for the continuous operation of the system.

COST ESTIMATION

BY calculating the cost of electronic components and the cost of manufacturing the system. The total cost is around 80 dollars. The cost can be justified as the single system can replace the need for 4-5 stalled systems which costs around 25-40 dollars. It is economical in that sense. This system can cover the area of 10km in a day. This can be properly patterned via GPS coordinates to cover the maximum size of the waterway.

CONCLUSION

Using the few of our systems the whole waterway of the city can be covered. Additional advantages like selected monitoring of data can be realized by this system. By this solution, we will revolutionize the safety and reliability of the water supply. This ensures the quality of water for a better life.

Inspiration

I am from the city of Rajahmundry. The city is on the eastern banks of the sacred Godavari River, in the southeast Indian. We worship the river as a goddess. But, due to recent industrial development and increased population. The river Godavari started to pollute. Millions of lives depend on the Godavari as it is the source of irrigation and drinking water. We do not want this situation to continue anywhere This inspires us to develop products and solutions which can ensure a better quality of water. This is our motivation to participate in this competition. We hope our solution can be utilized for a better future.
