Therefore, the indoor air quality requirements of higher and higher. The traditional indoor environmental monitoring facilities has poor real-time performance, low accuracy, large volume and single function, which is difficult to comply with the needs of modern economic development. Therefore, how to design a fully functional, simple, cost-effective indoor environmental monitoring system to become the trend. The design of the main content is to achieve a with temperature, humidity, smoke, formaldehyde and carbon monoxide is one of the multifunctional indoor environment monitoring system, the appropriate precision, applicable to family, office building indoor environment monitoring. The software design includes the overall software design, the design of each module, and the software code debug.. Each module includes: various sensors and data acquisition and processing, alarm, display, output drive module, host computer monitoring center of RS-485 communication module and PC man-machine interaction module. The main controller is STC89C52 microcontroller. A/D conversion uses ADC0832 to convert analog quantities to digital quantities. Combined alarm module and the motor as the ventilator output module, PC interface with Visual Basic 6.0 to design, monitoring in real time, the next bit machine indoor environment data. In practice, the data acquisition, conversion, display and transmission of each sensor can be completed, and
