The First Industrial Evolution

“We’ve got to pause and ask ourselves: How much clean air do we need?” Lee Iacocca Clean air Feeling drowsy ? Got a headache ? Hard to concentrate ? No worries. Check the CO2 levels in the office. If they are on the high side, go open a window and breathe some fresh air - or yell at the janitor in order to get him/her to fix the air conditioning. »

The LLC (Little LoRa Collider)

Some things are notoriously hard to test. Since we’re not designing our own gateway or packet forwarder (yet…), we end up having this third party “thing” between our beautiful Congress backend and our elegant EE02 LoRa modules. This “thing” being a LoRa gateway, which behaviour we simply have to trust. It should (in order to claim to be a LoRa gateway) reliably implement all the happy path scenarios needed for a successful LoRa deployment. »

It is - in short - a lora-as-a-service that we’ve built over the last year. Where is it? The console can be found at – register an account with Telenor CONNECT and it’s ready to use. »

Using AWS IoT with Congress

There’s a lot of different cloud IoT providers out there and Amazon is one of the biggest (if not the biggest). They started out relatively simple with EC2 and have added new services and features at a blistering pace the last few years AWS IoT is one of them. They have a fairly simple model: The devices are referred to as things (obviously), data from devices is stored in thing shadows and that’s about it. »

The wheels on the bus go round and round

…which may or may not affect the operation of our latest prototype. Only field testing will tell with any given degree of certainty. In late september, we were invited to a meeting with representatives from Telenor Reseach and the Northern Research Institute, which were on the lookout for mobile outdoors air quality sensors that could be mounted on bus rooftops in Tromsø, Norway. The sensor modules should be able to detect PM2. »
