Building a fully functional Prototype in 24h

Sensing particulate matter where it really matters.

Some background

Ben and I have developed a prototype that measures distance with a simple Arduino platform distance sensor. The data then gets uploaded to a TTNbackend via the LoRa protocol. Through a Node.js API we make use of the data by simply displaying a SVG that changes its state when the distance changes. This happens in real time and is mobile. We attached a 9v power source to this setup and took it for a walk. Because of our TTN gateway we placed at the window the coverage of the LoRaWAN is good enough to have a stable upload while moving many kilometers away from our gateway.
