In one's life 2/3 of the time is spent in the room. Indoor air quality portable intelligent monitor of this paper is to monitor and control the poisonous and harmful gases in indoor air as the background, based on STC, a 8 bit ultra low power microcontroller STC90C51 as the control core, realizes the indoor temperature, humidity, gas VOC real time acquisition and processing, display, alarm and other functions. The instrument is powered by a lithium battery, has good portability and versatility, and the use of LCD1602 dot matrix LCD display menu, has the good man-machine dialogue interface. While the design of sound and light alarm system, alarm in time for when the parameters exceed the standard. Monitor intelligent indoor air quality has the advantages of small volume, low power consumption, simple operation, sui...
