What can you do with a couple of IoT devices, Node.js, Elasticsearch, and MQTT? You can put together your own Internet of Things setup for measuring air pollution, like I have. In this blog post, I’ll share all the details about the hardware setup, software configuration, data analytics, an IoT dashboard, and MQTT broker-based integration with other tools from the IoT ecosystem, like Node-Red and Octoblu. Of course, I’ll also share a few interesting findings about air pollution IoT sensor measurements taken at a few locations in Germany. Take a look – doing this is much easier than you might think when you use the right tools!

Motivation

Recently, the Volkswagen Emission Scandal (Wikipedia) escalated again. Reasons were controversial animal experiments, as reported by The New York Times. This sparked numerous debates about banning Diesel cars from city centers in Germany, where I live. People talk about global car bans, but I’m amazed nobody is really talking about smart-city concepts yet. Besides the discussion around the cheating on nitrogen oxide emissions, the EU wants to enforce lower limits of particulates (measured in PM10 and PM2.5) in Germany. The impact on the health of high PM10 concentration is described in “Health effects of particles in ambient air”.
