H2OSupport will be a tool that any environmentally conscious person can utilize to determine the quality of a body or source of water. The device will feature many sensors, which will be operated by an Arduino microcontroller. These sensors will collect environmental data that will be transmitted by Wi-Fi or Bluetooth to a separate application. This application will be able to receive as well as analyse the data, produce pertinent reports and send alerts in some particular cases.
After an hour of research, here are some relevant sensors to consider:
| Sensors for Water Characteristics | Price ($) |
| Temperature | ~12 |
| Acidity – Potential of Hydrogen (pH) | ~30 |
| Oxidation Reduction Potential (ORP) | ~90 |
| Electrical Conductivity (EC) | ~40 |
| Total Dissolved Solids (TDS) | ~12 |
| Turbidity | ~10 |
I will post future updates for the project along the way.
