Automated Laboratory Monitoring based on the Internet of Things — •Nicolaj Betz1, Max Hänze1,2,3, Luigi Malavolti1,2,3, Gregory McMurtrie1,2,3, and Sebastian Loth1,2,31University of Stuttgart, 70569 Stuttgart, Germany — 2Max Planck Institute for the Structure and Dynamics of Matter, 22761 Hamburg, Germany — 3Max Planck Institute for Solid State Research, 70569 Stuttgart, Germany

Precise environment control is a crucial factor for reliable scanning tunneling microscopy. The Internet of things is a network of devices and appliances that combine measurement and control features with a connectivity framework, thereby introducing the possibility of remotely monitor and control laboratory setups [1]. Here we present an implementation that is based on battery-powered microcontrollers and Wifi connectivity to enable the use of conventional lab equipment in a cloud-based measurement system. Our approach enables precise process monitoring and control of a sub-Kelvin high magnetic field scanning tunneling microscopy laboratory with a small budget.
