摘要: 针对目前小型甲醛测试仪价格高、灵敏度低等缺点,设计了以STM8单片机为主控芯片、基于新型纳米材料传感器的高灵敏智能甲醛测试仪.该测试仪通过采样气路的设计和高精度信号采集电路,实现了对甲醛气体的高灵敏度、高精度的测量:其最小甲醛检测浓度为0.03 mg/m³,分辨率达0.01 mg/m³.测试仪采用了低电压、低功耗设计,由单节3.7 V锂电池进行供电,续航时间达8 h以上.同时,该测试仪集成了无线充电和无线蓝牙通信功能,能与手机、PC等个人智能终端设备进行数据通讯.测试结果表明,在0~3 mg/m³范围内,该甲醛测试仪检测结果与标准气体甲醛浓度的偏差小于2%,优于其他测试仪.

Abstract: Aimed at the defects that the small formaldehyde detector had high price and low sensitivity currently, a smart formaldehyde detector with the microcontroller of STM8S which had high sensitivity and precision based on a new nano material sensor was designed.With a special gas path and high precision signal acquisition circuit, the detector achieved the high sensitivity and high precision measurement of formaldehyde gas.It could sense 0.03 mg/m³ formaldehyde gas, and the resolution was 0.01 mg/m³.The detector designed by low voltage and low power was powered by a 3.7 V lithium battery and could work more than 8 h with optimized power consumption design.Wireless charging and Bluetooth technology were integrated into the detector which made the detector communicate with mobile phone, PC and other personal intelligent terminal equipment.Test results showed that in the range of 0~3 mg/m³, the deviation the deviation of the detection result of the formaldehyde detector was less 2% and it was superior to other detectors.
