Introduction
Topics:
- air quality sensors
- ammonia
- NOx
- water chemical analysis
- nitrates
- ammonia
- dissolved oxygen
- sulfide/sulfate
- phosphates?
- salinity (chlorides?)
- water physical analysis
- temperature
- clarity/turbidity -> investigate standard ways of measuring/expressing this
- conductivity/total dissolved solids
- water properties by light reflection, hyperspectral/polarity
- boat control
- trajectory -> steering
- camera control
- post-processing
- data presentation
- video/photo stitching
- time lapse view
- map view of properties
- data presentation
- use cases
- verify with domain experts, how to engage?
- slootview, under/above water
- minimum viable prototype
- high-res measurement by location, by time
- materials
- boat selection
- processing platform selection
- communication platform selection
Air quality sensors
Nitrogen compounds in air
According to https://www.rivm.nl/stikstof/monitoren-advies-onderzoek/overzicht-stikstofmetingen/metingen-stikstof-in-de-lucht average (typical?) values of
- Ammonia (NH3): 6.7 ug/m3 (9.6 ppb)
- NOx: 27.3 ug/m3
- NO2: 18.6 ug/m3 (9.9 ppb)
(ppb-conversion using https://www.breeze-technologies.de/blog/air-pollution-how-to-convert-between-mgm3-%C2%B5gm3-ppm-ppb/ )
RIVM report on inexpensive nitrogen-in-air sensors: https://www.samenmeten.nl/sensoren-voor-no2 Conclusion: most sensors are not sensitive enough to be used in typical outdoor conditions, with perhaps one exception: alphasense NO2-B43F
Use cases
material:
Reeuwijkse plassen
See
- https://www.rijnland.net/wat-doet-rijnland/in-uw-buurt/reeuwijkse-plassen/ their stated goal: CLEAR WATER
- https://www.rijnland.net/regels-op-een-rij/subsidies-en-andere-financi%C3%ABle-bijdragen/
goals:
- slootview, inspect water sides over time
- underwater camera: detect invasive cray fish
- sample water properties at high spatial resolution
- detect indicators for cyanobacteria: temperature and nutrients
