The author of the article has been working with InfluxDB's 2.0 Alpha releases and was excited about the new features, particularly those related to IoT data processing. The author built a system that streams data from various sensors to InfluxDB and used Flux, a query language for InfluxDB, to perform cross-measurement math calculations. The author used this ability to compensate for temperature and atmospheric pressure effects on CO2 readings from a sensor, which is a game-changer for IoT data processing in InfluxDB.
