基于物联网技术的便携式甲醛检测仪的设计与实现

Design and implementation of portable formaldehyde detector based on Internet of things

本文提出一种基于物联网可靠传输的便携式甲醛检测设备的设计方案,整个系统首先通过高灵敏度的甲醛检测模块采集当前环境下的甲醛浓度值,并在完成模数转换后将甲醛值传送至单片机控制端,单片机再通过蓝牙传输模块将测量值传送到手机端,同时,甲醛检测设备机体也可以通过LCD1602液晶显示器显示当前环境下的甲醛浓度值。当检测值超过系统预设的最大安全浓度值后,会在手机端和机体端同时触发报警。通过系统测试,该系统具有使用方便、运行稳定、检测精准度高、人机交互性好等优点,具有一定的市场经济价值。

In this paper,we propose a design scheme for a portable formaldehyde detection device based on the Internet of things reliable transmission,and the whole system first collects the formaldehyde concentration value under the current environment by a highly sensitive formaldehyde detection module,and delivers the formaldehyde value to a single-chip control end after completing analog-to-digital conversion,and a single-chip again transmits the measurement value to a mobile phone end via Bluetooth transmission module,and at the same time,Equipment for formaldehyde detection the body can also show the value of formaldehyde concentration under the current environment through an LCD1602 liquid crystal display.When the detection value exceeds the maximum safe concentration value preset by the system,the alarm is triggered at the mobile phone end and the body end simultaneously.Through the system test,this system has many advantages,such as convenient use,stable operation,high detection accuracy and good human-machine interaction,which can have a certain market economic value.
