On university campuses, students Dormitory or campus Management has long been one of the school’s key priorities, and the enforcement of the tobacco‑free policy is an essential measure for safeguarding a healthy campus environment.

Recently, primary and secondary school students, in pursuit of the so‑called… The “cigarette‑card trend” even encourages teenagers to try smoking and use it as a form of currency, a practice with far‑reaching consequences. Smoking among minors not only harms their respiratory system and accelerates the decline of cardiopulmonary function, but may also lead to a range of chronic diseases, severely compromising their growth and development.

Moreover, such harmful behaviors can easily give rise to unhealthy social habits and distort values, thereby negatively impacting academic performance and future life. All sectors of society should attach great importance to this issue, strengthen education and guidance, foster a healthy, smoke-free environment for young people, and safeguard them from the dangers of tobacco.

 

In order to effectively supervise students Dormitory or campus In response to indoor smoking, intelligent smoke‑free solutions have emerged. We will introduce a system based on cigarette‑detection sensors, LoRa Intelligent students of communication gateways and alarm control panels Dormitory or campus Smoking ban solutions,

Aimed at improving the school Dormitory or campus Enhance management efficiency and foster a positive learning and living environment.

Cigarette detection sensor

The cigarette detection sensor is one of the key components of an intelligent smoking‑prevention solution. By installing the cigarette detection sensor on students… Dormitory or campus Key areas, such as corridors and restrooms, can be monitored in real time. Dormitory or campus The smoke concentration inside.

The sensor boasts high sensitivity and accuracy, enabling it to reliably detect smoke and promptly issue an alert.
