The essential idea for this project is to collect significant data from the waterways for monitoring the water quality. From the analysis of the collected data, unhealthy water can be treated as soon as possible from the respective authorities. A monitoring system consisting of a water capsule with sensory devices, microcontroller, and communication device is developed and the system is named as Qwater. To prolong the life of the batteries, a solar panel is installed on Qwater. The energy saving technique is implemented to sustain the lifespan of Qwater.
How it works
The Qwater system is used for data collection. The collected data includes water acidity (pH), water temperature, total dissolve solid (TDS), dissolved oxygen level and turbidity. A microcontroller (Arduino or Raspberry Pi) is programmed to transmit data to a gateway via cellular network. It transmits data once every 6 hours and will remain in idle mode to conserve power consumption. The data is stored in a cloud database (Google Cloud Platform) and is analyzed for pre-intervention action. The results are visualized in a dashboard created using Python-based machine learning. If abnormalities occur, an alert system is triggered and the respective authorities are notified. The collected data is further employed for the water quality prediction by using a Long-Short Term Memory (LSTM) Deep Neural Network algorithm.
What makes it novel/innovative/specialty
With the development of the Qwater system, sensing, collecting and analyzing the 5 parameters simultaneously will produce a better monitoring system and instant remedial action. Storing data in the cloud database and visualizing the data on a dashboard makes the water quality surveillance tasks easier and efficient as data can be traced back anytime. The system includes alert notifications whenever the threshold water quality is reached. Furthermore, analysis of the data using the LSTM Deep Neural Network algorithm can predict the water quality 6 months ahead in the future so that preventative action can be taken. Attachment of a solar panel and frequency for data transmission can extend the battery lifetime and reduce the maintenance cost and time.
How it would be produced/manufactured
Where it would be applied
The Qwater can be deployed in major waterways such as water source from lakes and rivers. This is to ensure the source is clean and unpolluted. Qwater can be deployed at the industrial water treatment plant and reservoir to monitor and ensure the water is not contaminated before it is released into the river. The waterways near farming, agriculture, housing and factories are also be monitored with Qwater sensors to supervise the discharged wastewater.
