This is a small tutorial how to create a time series graph in RRDTool using Gravio Edge IoT CO2 sensor data. While this tutorial refers to the IoT Platform Gravio, parts of it can be applied independently of the IoT Platform as long as you have your data in a format that allows you to inject it into the RDD Database using the command line.

What we learned when deploying Gravio in a small Swiss Cheese Shop in Central London.

Lenovo Japan GK develops and sells a range of hardware, including servers, tablets and PCs, and boasts the top share in the global market. With Gravio, Lenovo was able to improve the use of conference rooms at the Japan head office and increase efficiency for the Operations team. By combining Gravio with Lenovo’s own Edge PC, we succeeded in introducing a conference room management system at low cost and in a short period of time.

Gravio supports a range of different sensors, and we’re often asked questions about these sensors, including about when their data is sent to Gravio. Here we explore some of the sensors Gravio supports, and give guidance on how often they typically send data and under what conditions and circumstances.
