Inspiration
In 2022, Forbes reported that 60% of water wells on the continent of Africa failed because of poor maintenance and a lack of access to quality replacement parts. This results in them collecting water from unsafe sources. Water collected from the wells also get easily contaminated because people do not have the tools or knowledge to test the water. We aim to fix this issue sustainably at a low cost to ensure everyone has access to clean and safe water.
What it does
Our idea is a early detection warning system to detect and ensure water quailty. Our sensors include a MPU6050 accelerometer and a SEN-WAT-013 analog TDS sensor. The sensors are linked to our app called "Well well well..." where it would analyse the data and remind locals what they are required to do. The accelerometer is used to detect the vibrations produced by the handle. We plan to use the vibrations detected to identify if there are any loose parts in the well before it reaches a stage where they are unable to fix it anymore. When there are deviations in the vibrations, it will send notifications to inform locals to check screws, grease parts or clear debrises in the well. Our water sensors are used to test the safety of the water. The app will inform them if the water is safe to drink.
How we built it
We build an app using JavaScript - React Native app development, while using expo as a framework. C++ - ESP32 firmware development with Arduino IDE to upload code to our ESP32 C6 XIAO microcontroller JSON - Data exchange format between ESP32 and React Native app
Challenges we ran into
Integrating the 2 sensors into one system through wiring and circuitry Linking the sensor data to the developed app
Accomplishments that we're proud of
Connection between real time sensor values and app Proper connectivity of the entire system
What we learned
Troubleshooting on C++ Arduino IDE Coding of an app using Javascript
What's next for Well well well...
We plan to create a better housing for the sensors and add more sensors to fully ensure that the water quality is safe. We also plan to work with organisations so that they can distribute our product whenever they are building new wells and give shorts lessons on the most basic maintence of the well when our app informs them to check.
