Modular Open-Source Stirred Tank Reactor (MOSTR)

This repository contains data related to the open-source, Internet of Things (IoT)-enabled Modular Open-Source Stirred Tank Reactor (MOSTR), developed for teaching chemical engineering principles such as residence time distribution, flow balancing, and process instrumentation within higher education laboratories. The system is designed as a low-cost, educational informed, modular alternative to commercial teaching units and allows the simultaneous deployment of multiple rigs to enhance engagement and inclusivity in practical learning at scale. The reactor integrates an M5Stack-based control unit with flow, temperature and conductivity sensing and real-time data streaming via wi-fi and Virtual Machine (VM) server infrastructure. The design emphasizes open source reproducibility using accessible fabrication techniques such as 3D printing and prioritises maintainability and pedagogical alignment. All design files, firmware, and documentation are shared under a CC BY 4.0 licence to support adoption and adaptation in open engineering education.
