Design of Environmental Monitoring System for Subway Machine Room

In order to ensure the stable and reliable operation of the electronic computer system in the subway machine room and maintain a good working environment for the staff, strict control of the machine room environment is necessary. Based on this, this article uses the STM32 microcontroller as the core controller, combined with external sensor circuits and 4G wireless communication technology, to design a subway machine room environment monitoring system. The system can monitor the machine room environment in real-time through a mobile app, When there is an abnormality in the data, the buzzer will directly alarm. This system can monitor real-time parameters such as the environment of subway machine rooms, which has significant practical significance for the maintenance of machine room equipment and ensuring the personal safety of staff.
