⁠About

Precision Water One (PWO) is a smaller, versatile, cost-effective and energy efficient water quality monitoring system for industry, educational, and research applications. The solution will collect water quality, considering five parameters to start: Dissolved Oxygen (DO), Electric Conductivity (EC), PH+, Temperature, and Water Flow; with expansion capabilities to include other sensors.

⁠Overview and Background

It is known that measuring and monitoring water quality parameters (DO, EC, PH+, among others) allow to mitigate the risks of contaminated water human ingestion.

⁠Hardware Components

To measure and monitor water quality with less human intervention. This project combines the following hardware components:

• Raspberry Pi 4 Board
• ESP32 Development Board
• Whitebox T3 (Atlas Scientific)
• High-Precision AD/DA Expansion Board
• Water quality sensors.
• Waterproof IP65/66 case.

For more details, please refer to Hardware Folder⁠

⁠Software Components

The project integrates:

• IOTA Streams API (developed by Zignar Technologies) which can be use to create authors/subscribers, and send/fetch messages to IOTA Tangle (blockchain).
• InfluxDB
• Grafana
• Node-RED
• MicroBlocks (ESP32 programming)
• Docker

For more details, plese refer to Software Folder⁠

⁠Standards

This project is based on IOTA Streams Framework⁠. The API Streams was developed using Rust Programming Language and the sensor reading was developed using Python.

⁠Potential

All the components are Open Source to allow free usage and continuous improvements by the community. The first insitution who benefits from this project is Lethbridge College (source)⁠, but many other similar education institutions can be benefited as well.

⁠Future Steps

Regarding use cases, the next steps are:

• IOTA Decentralized Identity → for device identification. Also, to issue certifications for the students who have been trained about IOTA with this project.
• IOTA Non Fungible Tokens → to make the digital twin representation of each device unique, and to link the NFT metadata with a Data Stream.
• IOTA Smart contracts → to enable data commercialization from IoT devices.

Regarding the community, the next steps are:

• Increase colleges and other educational institutions using the technology.
• Reach non crypto communities of developers and engineers to present the project.
• Increase the number of individual developers engaged with the project.
