2. Problem & Purpose
● Freshwater Monitoring and Communication
✓ River Eutrophication
✓ Draining hazardous sewage from an
electroplating factory
✓ Sighting of massive fish kills in the Keelung
River after the typhoon
● Sustainability
✓ Protecting ecosystems

3. Solution - Salmon submarine
● Specific
✓ A submarine is released at the source of a river upstream
and automatically returns to its origin after reaching the sea
● Environment Seneor
✓ Sensors for monitoring temperature, colors, oxygen level,
and water pressure; GPS, etc
● Internet of Things (IoT)
✓ Data collection from Sigfox and storage to cloud
● Sample
✓ Turn on Solenoid valve and return with collected abnormal samples

4. Releasing the submarine at the source of a
river

5. Collecting data and uploading GPS location, real-time
environmental information to Sigfox

6. Centralizing monitoring and preventing illegal draining of sewage

7. Automatically returns to its origin after reaching the sea

8. After data collection
● Advance water quality testing
✓ Liquid Chromatography
✓ Algae analysis
● Historic data
✓ Storage data to cloud
✓ Environmental condition analysis
✓ Video record analysis

19. Q & A
● What if I need more and different kinds of electrochemistry sensors?
Make a cluster of Microcontrollers, and communicate each other with SPI or I2C protocol.
● Once the submarine is stuck, how do I know?
We didn’t perform this function in the project, but we can do that! There is an accelerometer on
UnaShield V2S, we can estimate the magnitudes of every axis, and set thresholds for that.
If the magnitudes are less than the thresholds during the detecting period we defined, it means
the submarine is stuck.
