Nick Masson from Multitude Inc won the hackathon by developing a system to measure air quality inside buildings and cities using LoRaWAN CO2/NOX sensors connected to modules that send data every 30 seconds to TheThingsNetwork platform and a dashboard. Boyana Norris from the University of Oregon was the runner-up by using an ultrasound and light sensor with an mDot module to pull data from TheThingsNetwork into Spark to discover relationships between data sets and potential applications for building occupancy and measuring advertisement engagement. The hackathon was hosted by the LoRa Alliance to enable connectivity for IoT devices globally using the LoRaWAN protocol.
