Abstract:This paper introduces the design Of the indoor environment monitoring system based on STC12C5A60S2 MCU, the system consists of indoor environment monitoring module and display module, the DHT21 temperature and humidity sensor MS1100 and formaldehyde sensor,realizes the monitoring function Of the indoor environment, and the monitoring data is converted by STC12C5A60S2 microcontroller, which display in the display module out. The system can not only effectively monitor the indoor environment, but also have many advantages,such as I ight,small, IOW consumption and SO on.
