A Cost-Effective Modular Data Logger for Detector Laboratories — •Philip Hauer, Mario Engel, Oliver Adam, Thomas Block, Jan Paschek, Tobias Rudolph, and Bernhard Ketzer — Helmholtz-Institut für Strahlen- und Kernphysik – Universität Bonn

Many important parameters of a gaseous detector (e.g. the gas gain) depend on environmental parameters such as pressure and temperature. For the operation of gaseous detectors it is therefore crucial to monitor these parameters precisely and reliably. In order to fulfil this task, a modular logger for environmental parameters in laboratories was developed. In addition, the used temperature and pressure sensor is so small that it can be placed inside the gas system such that it can measure the temperature and pressure of the gas directly.

The logger is based on different sensors that are connected to a micro-controller which has a built-in WiFi chip. The micro-controller connects to a local wireless network which is created by a Raspberry Pi. Via the MQTT protocol, the recorded data are sent to the Raspberry Pi which forwards the data to a remotely accessible database for long-term storage.

On this poster, the setup is described in more detail. Some exemplary data and how they are used to correct gain fluctuations are also shown.
