On the topic of water quality several initiatives have already been started with Sensemakers. When you pass by the Marineterrein you’ll notice the yellow Lego-head in the water. We also have several sensors in the sewer to test wateroverflow.We still could use further development on:
- Water quality sensors (KnowFlow): to measure several properties of water, a complete set of sensors and hardware is readily available. The idea is to start with a well documented kit: https://publiclab.org/notes/shanlter/06-08-2017/knowflow-automatic-water-meter
From there we can improve and add components:
– Anti fouling casing (to prevent rapid contamination of the sensors
– Wireless connectivity (LoRa)
– Additional or improved sensors (like the conductivity sensor from Sodaq)
– Water level sensor for detection of sewer overflow
– Comparison of different types of sensors (ultrasonic, Time of Flight (laser), capacitive, static pressure
– Improvement of power usage
– Test of different wireless methods from the sewer (LoRa, NBIoT, LTE)
– Visualization of measurements on a website (back-end and front-end development) - Water flow sensors for sewer pipes
– Experimental with different sensors (bending, dynamic pressure, temperature gradient
– Visualization of flows - Test aquarium
Ecocube & Open Aquarium: a (Aquaponics) aquarium that could be used to test waterquality sensors indoors https://getecoqube.com and https://www.cooking-hacks.com/documentation/tutorials/open-aquarium-aquaponics-fish-tank-monitoring-arduino/ - 2017 project, check this site!
