With the improvement of people’s material living standards, they have also put forward higher quality requirements for the living environment, but the resulting toxic gases such as formaldehyde, toluene and organic volatiles brought about by decorations are fatal to human health. To this end, this paper designs one odour sensor-based toxic gases concentration monitoring system for indoor decoration: at the front end of the system, it is equipped with an independently-developed highly sensitive formaldehyde sensor; Wi-Fi technology with high stability and long transmission distance is selected as the main information transmission method; the front-end monitoring circuit can monitor the environmental parameters such as temperature, humidity, formaldehyde concentration, and CO concentration of each unit in real time; the design of the Web interface is based on the development of SpringMVC3+Hibernate3 development software and Oracle11g database. Finally, through the test of the toxic gas concentration monitoring system for indoor decoration, it’s found that it works stably in line with the design requirements.
