摘　　要：介绍了一种基于PIC单片机的手持式空气质量监测仪。该监测仪由锂电池供电,利用半导体和红外光学传感原理,实时检测大气中有机污染物和烟尘的含量,具有液晶显示和超限声光报警功能,并能通过触摸键盘自动标定。该仪器具有功耗低、智能化程度高、适应性强的特点,是很有前景的在线式工业或实验室用仪器仪表。A handheld air quality monitor based on PIC MCU is introduced. The monitor is powered from a Li-ion battery cell, and relied on a semiconductor and an infrared optical sensor principle, so concentration of odorous gas and dust particles can be detected in time. Functions such as LCD display and sound-flash alarm in case of limit exceed, self calibration by touch key- board are also achieved in this monitor. The advantages of low power consumption, high intelligent, strong adaptability, and etc make the monitor a promising in-field instrument using in industry or laboratory.
