Smart home products are widely used in the fields of anti-theft alarm and building control; from the perspective of users, the market demand for home control, home environment and entertainment is more urgent.

From the perspective of disease prevention, in the home environment, carcinogenic gases (such as formaldehyde) volatilize and need to be detected to reduce the probability of cancer, leukemia or other chronic diseases caused by decoration pollution. Specifically, with the development of modern industry With rapid development, environmental pollution is becoming more and more serious. The reduction of air quality is not conducive to human health, and may cause disease or even death in severe cases. In today's society, where we spend most of our time indoors, indoor air quality is of utmost importance. The air contains toxic gas CO, formaldehyde, and dust particles, etc., which can cause symptoms such as headache, dizziness, nausea and glare. Therefore, it is particularly necessary to design a family carcinogenic gas content alarm for monitoring the indoor environment and ensuring the health of residents.

However, in the actual application process, if the gas content alarm is to be carried out, the gas content must be detected.
