Environmental monitoring system for silicon detector testing and beam telescope operation

This report discusses the motivation for, preparation and final implementation of a monitoring system for CLICdp Timepix3 beam telescope used to test small semiconductor devices at the CERN SPS North Area test beam facility. The final hardware setup is based on an arbitrary number of Raspberry Pi’s that read out the system’s sensors and serve as webservers passing on the acquired data for further analysis and visualization. The processed data is stored in an SQL database and displayed in the Grafana GUI run as an instance under Platform-as-a-Service. In its current configuration the system processes measurements of temperature, humidity and airborne particulates. It also collects and displays state variables related to the operation of CLICdp Timepix3 beam telescope.
