摘　　要：测量准确、响应迅速和携带方便是气体检测仪的特点,物联网技术的应用推动了气体检测仪的进一步发展。以ATmega8单片机为核心器件,以电化学式气敏元件作为传感器,以OCM12864-9图形点阵式液晶显示模块作为显示器件,设计测量电路和数据处理程序,制作多功能手持式有害气体检测仪。该检测仪在实地测量中取得了良好的效果。Accurate measurement, fast response and easy to carry are the characteristics of the gas detector. Internet of things technology promotes the further development of the gas detector. Taken ATmega8 microcontroller as the core device, the electrochemical gas-sensitive element as the sensor and OCM12864-9 graphics dot-matrix LCD module as a display device, the measurement circuit and data processing program are designed, and the multi-function handheld harmful gas detector is made, which has a good result in the field measurement.
