Ocean Watch

Inspiration

Ocean water quality sensing is important to identify the impact of human activities on the aquatic environment and ecosystem. It directly impacts our health and economy. An algal bloom, caused by excess nutrients pollution in water, is harmful to aquatic life.

What it does

Ocen water quality sensing unit

Here, we developed a hardware system for ocean water quality sensing. Users can view different parameters of water quality such as

Air temperature
Air humidity
Water temperature
pH
Turbidity
GPS(location)
TDS (total dissolved solids)
Water level

Dashboard

users select points on the map to view parameters including pH, TDS, water temperature, air temperature, humidity, water level, dissolve O2 level

How we built it

Front-end development using html, css, javascript, apex charts and d3.js
Back-end development using python
Hardware development using C++ and ESP32

Sensors used

Analog TDS Sensor
pH Meter with breakout Board
DHT11
Waterproof analog temperature probe
SEN0189 Turbidity Sensor
Analog Water Level Sensor
Phone GPS

Challenges we ran into

We are an international team with 4 timezones, not all developers are awake at the same time. We overcame this by effective planning and communication.
We had trouble accessing the satellite images dataset to identify harmful algae bloom. By the time he had access to it, it was too late to implement it.
