摘　　要：根据市场上甲醛检测装置存在误差大、功耗高等缺点,设计了以MSP430单片机作为控制核心,多子机网点辅助监测,无线模块进行数据通信的甲醛检测仪。使用单片机内部A/D转换模块将传感器采集到的模拟量转换成数字量,再经卡尔曼滤波器进行滤波,保证了采样数据的准确性。该监测系统检测精度高、功耗低、稳定性好,经试验验证,能很好地满足消费者需求。At present, the formaldehyde detection device on the market have many limits such as large error and higher power consumption. This paper designs a kind of formaldehyde detector which chooses MSP430 single chip microcomputer as control core, multiple outlets to auxiliary monitoring, and the wireless module for data communication. The analogue which has been collected by sensor can be converted to the digital quantity using the internal A/D conversion module in single chip microcomputer, and then be filtered by the Kalman filter, at last the precise sampling data can be guaranteed. This monitoring system can meet the needs of consumers well with the high precision, low power consumption and good stability which is verified by test.
