Arduino Uno Multi-Sensor Water Quality Monitor¶
Water Quality & Sensors • Est. CapEx: $25 USD • Lifespan: 7–15 Years
Technical Overview¶
An open-hardware IoT water quality monitoring prototype centered on the Arduino Uno microcontroller. The system uses a pH sensor, digital temperature probe (DS18B20), and turbidity sensor to assess water conditions in real time, providing simple visual feedback via red/green LEDs to indicate safe or unsafe water states.

| Standard Lifespan | 7–15 Years |
| Technology Maturity | Prototype |
| Primary Mechanism | Sensor analog and digital outputs are connected to an Arduino Uno core controller that continuously samples pH, temperature, and turbidity. Processed data is communicated wirelessly (with Zigbee mentioned as an option) to a centralized monitoring platform, while onboard LEDs deliver immediate local status indication for field operators without needing a screen or smartphone. |
