Transporting and storing data is a critical part of any remote sensor system. For Internet of Things (IoT) based system, handling large quantities of messages in an efficient and reliable way is critical for the success of the system. Our system, a network of IoT based, long distance environment sensors, is no exception. Message brokers

Interfacing a K30 CO2 sensor with a Raspberry Pi for Remote Air Quality Sensing
Climate change, and the declining air quality in major urban areas is becoming an increasingly prevalent and critical issue, with hundreds of thousands of premature deaths due to air pollution in Europe alone (http://www.bbc.co.uk/news/world-europe-38078488). One approach to resolving this problem is a data-driven “Smart City”. So-called Smart Cities employ a huge network of sensors all
