Design of a Monitoring and Alarm System for Gas Heating Bathroom Based on STM32

Now, more and more families use gas heating system in the bathroom, however, there might be potential safety hazards such as carbon monoxide(CO) poisoning. Therefore, it is crucial to reduce or lower the safety risks when people bathing. This paper designs a monitoring and alarm system for gas heating bathroom based on STM32, realizing real-time monitoring, display, alarm giving, and other functions combined with a Wechat mini program and Alibaba Cloud Internet of Things(IoT).

I. Introduction

In China, If a gas-fired water heater is used in the family bathroom, the carbon monoxide(CO) concentration is prone to exceed the standard. Judging the safety of the bathroom environment by human sense lacks accuracy. Once there is a danger in the bathroom, it is difficult for the person in the bathroom to react after sensing the danger, while people outside the bathroom cannot know the specific situation inside, thus missing the rescue opportunity.
