This paper introduces the multi-function measurement system based on the SCM STC12C5A60S2. The system can realize the following functions, such as the detection of air temperature and humidity, CO2 concentration, and indoor light intensity. At the same time, it also has a function of calendar and clock display. The design of hardware and software, the choice of components, and the design of unit circuits and the circuit connection of the system are described also. Through theoretical analysis and experiment, it is demonstrated that the system can detect the temperature, humidity, CO2 content and indoor light intensity effectively, and features accurate measurement, convenient parameter adjustment and good use effect..
