Description
技术领域
[0001] 本实用新型涉及空气质量检测技术领域，特别是一种空气质量检测仪。
背景技术
[0002] 目前，检测空气中甲醛的仪器为分光检测仪，通过气体和试剂的反应产生颜色变化，再通过专门的仪器读出对应的颜色值，缺点是检测慢，整个检测流程需要30分钟左右；另外分光检测仪操作需要专业人员操作使用，非专业人员操作有可能检测的值不准；其次在室内甲醇浓度分布不均匀，分光检测只能测房间固定点的甲醇含量，无法实时检测，且测量精度低，最小分辨率为0.01mg/m3。
发明内容
[0003] 本实用新型要解决的技术问题是针对现有技术的不足，提出一种检测速度快、操作简单、检测精度高的空气质量检测仪。
[0004] 本实用新型要解决的技术问题是通过以下技术方案实现的。本实用新型是一种空气质量检测仪，其特点是:包括单片机处理器、显示模块、按键模块、甲醛传感器、放大电路模块、A/D转化模块、VOC传感器、温湿度传感器和电源模块；其中，单片机处理器分别与显示模块、按键模块、A/D转化模块、VOC传感器、温湿度传感器、电源模块相连接；单片机接收A/D转化模块、VOC传感器、温湿度传感器、按键模块的信号，单片机向显示模块发送信号；所述甲醛传感器依次连接放大电路模块、A/D转化模块，甲醛传感器将采集的信号经过放大电路模块放大后，传输给A/D转化模块。
[0005] 本实用新型一种空气质量检测仪技术方案中，进一步优选的技术方案特征是:
[0006] 1、所述电源模块包括USB端口、充电电路模块、锂电池、开关机电路模块、电源稳压模块；所述USB端口依次连接充电电路模块、锂电池、开关机电路模块、电源稳压模块，所述单片机处理器分别与充电电路模块、开关机电路模块、电源稳压模块相连接；
[0007] 2、所述单片机处理器采用STC89C52处理器芯片；
[0008] 3、所述显不_旲块米用液晶显不屏；
[0009] 4、所述甲醛传感器采用CH20传感器；
[0010] 5、所述VOC传感器采用MSllOO传感器；
[0011] 6、所述温湿度传感器采用DHTll温湿度传感器。
[0012] 与现有技术相比，本实用新型一种空气质量检测仪具有检测速度快，开机I分钟后可读出准确的实时数据；且操作简单，非专业人员只要开机就能检测；本实用新型一种空气质量检测仪可实时检测，可随时检测室内不同地点的空气质量指标；且检测精度高，分辨率可达0.001mg/m3。
附图说明
[0013] 图1为本实用新型的结构示意图。
具体实施方式
[0014] 以下参照附图，进一步描述本实用新型的具体技术方案，以便于本领域的技术人员进一步地理解本实用新型，而不构成其权力的限制。
[0015] 实施例1，参照图1，一种空气质量检测仪，包括单片机处理器、显示模块、按键模块、甲醛传感器、放大电路模块、A/D转化模块、VOC传感器、温湿度传感器和电源模块；其中，单片机处理器分别与显示模块、按键模块、A/D转化模块、VOC传感器、温湿度传感器、电源模块相连接；单片机接收A/D转化模块、VOC传感器、温湿度传感器、按键模块的信号，单片机向显示模块发送信号；所述甲醛传感器依次连接放大电路模块、A/D转化模块，甲醛传感器将采集的信号经过放大电路模块放大后，传输给A/D转化模块。
[0016] 所述电源模块包括USB端口、充电电路模块、锂电池、开关机电路模块、电源稳压模块；所述USB端口依次连接充电电路模块、锂电池、开关机电路模块、电源稳压模块，所述单片机处理器分别与充电电路模块、开关机电路模块、电源稳压模块相连接。
[0017] 所述单片机处理器采用STC89C52处理器芯片。
[0018] 所述显不t旲块米用液晶显不屏。
[0019] 所述甲醛传感器采用CH20传感器。
