基于STC12C5A60S2单片机的室内环境检测系统设计

介绍了基于STC12C5A60S2单片机的室内环境检测系统设计方法。为了对室内不同环境（包括客厅、卧室、厨房和卫生间）的不同参数进行实时检测，整个系统以客厅为核心，将实时检测到的卧室、厨房、卫生间等处的环境参数值传送给客厅系统，实现了对室内不同环境、不同参数的实时检测和显示。当室内环境中的CO浓度、NH，浓度、H2S浓度、煤气浓度或甲醛浓度超标时，系统会自动报警，同时根据实时检测到的温、湿度和光照度值来决定电器（如空调、加湿器、灯具）的开关状态，以达到节能的效果。该系统简单，可靠性强，成本低，可扩展性好。

Design of Indoor Environment Detecting System Based on STC12C5A60S2 Microcontroller

A design method of indoor environment detecting system based on STC12C5A60S2 microcontroller was introduced. In order to detect different parameters in the real time in different indoor environment, including the sitting room, bedroom, kitchen and toilet, the whole system centers on sitting room system, transmits the environment parameters detected from bedroom, kitchen and toilet respectively to the sitting room system, realizes the detection and display of different parameters in different indoor environment. When the concentration of CO, NH3 , H2S, coal gas and formaldehyde in the indoor environment is higher than respective criterion, the system will alarm automatically based on the temperature, humidity, intensity of illumination detecting, the system decides to open or close household appliances in order to get the result of energy saving. The system is simple, it has strong reliability, low cost and good expansibility, and it can be used in the intelligent community.
