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/
