摘要
设计了一种高灵敏度甲醛传感器,该传感器采用了高比表面积的氧化镍(NiO)纳米材料,通过丝网印刷技术制备,可实现对ppb级甲醛气体浓度的检测。基于单片机STM8S208和无线蓝牙通信模块,集成PM2.5传感器、挥发性有机物(VOC)传感器、温度和湿度传感器,开发了可无线通信的多参数空气质量监测仪。实验表明,设计的监测仪测试结果准确、运行可靠、成本低廉,适合作为智能家居系统中的空气质量监测节点。
A high sensitivity formaldehyde sensor was designed and fabricated based on nano-material of Ni O and screen printing technology.With high specific surface area of the sensitive material,the sensor can detect formaldehyde gas even at ppb level.Furthermore,a smart multi-parameter air quality monitor that can wirelessly communicate with external device was developed based on STM8 S208 and Bluetooth module,and integrated with PM2.5 sensor,VOC sensor,temperature and humidity sensor.Experiments show that the results are accurate and stable,and the monitor is suitable to be used as an air quality monitoring node in smart home system with low cost.
