<h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">* 1、项目功能介绍</h3>
<p><span style="font-family: 宋体;"> <span style="color: #000000; font-family: arial, helvetica, sans-serif;">随着时代的进步和经济的发展，我国的汽车数量也越来越多。在日常生活中，汽车提高了我们的办事效率，汽车成为了一部分人们生活的第二空间。但是汽车空间狭小、密闭性强，如果有害气体超标，对身体健康影响非常大，严重情况下更会导致免疫力下降、肝脏疾病、白血病、癌症等疾病，特别是对孕妇、婴儿、儿童的健康影响比较大。虽然很多汽车厂家针对这些问题研发出了具有空气净化功能的汽车，但在实际使用中，我们无法了解车内空气中的污染物质浓度。虽然有专业的检测结构，可以提供车内空气污染物浓度检测的服务，但是也存在价格昂贵、无法实时检测的弊端。为此，我设计并制作了一款车载环境卫士，可以有效的实时检测车内空气中的污染物是否超标。</span></span></p>
<p><span style="font-family: 宋体;"><span style="color: #000000; font-family: arial, helvetica, sans-serif;"><strong>温湿度检测</strong>：当车内环境温度过高，不仅容易引起中暑等身体损伤，还会导致内饰材料释放VOC等有毒物质，影响驾乘人员的身体健康。当温度过高，车载环境卫士会进行蜂鸣器等报警，提示司机进行降温。</span></span></p>
<p><span style="font-family: 宋体;"><span style="color: #000000; font-family: arial, helvetica, sans-serif;"><strong>湿度检测</strong>：当车内湿度过高，也会影响身体健康，车内也很容易滋生细菌和异味。当湿度过高，车载环境卫士会进行蜂鸣器等报警，提示司机打开空调进行除湿。</span></span></p>
<p><span style="font-family: 宋体;"><span style="color: #000000; font-family: arial, helvetica, sans-serif;"><strong>VOC气体检测</strong>：随着时间的变化和温度的变化，汽车内饰会释放出VOC气体，对身体有伤害。当车内VOC气体过高时，车载环境卫士会进行蜂鸣器等报警，提示司机进行通风或者打开空气净化。</span></span></p>
<p><span style="font-family: 宋体;"><span style="color: #000000; font-family: arial, helvetica, sans-serif;"><strong>CO2气体检测</strong>：车内空间狭小,当车内CO2达到一定值时,人就会出现昏迷和脑缺氧，导致犯困、反应速度降低。当车内CO2气体过高时，车载环境卫士会进行蜂鸣器等报警，提示司机进行通风。</span></span></p>
<p><span style="font-family: 宋体;"><span style="color: #000000; font-family: arial, helvetica, sans-serif;"> 此外设计了<strong>孕婴模式</strong>，在设置中开启孕婴模式后，各个指标的报警值会更低，报警更灵敏，为孕妇和婴儿的身体健康保驾护航。还可以设置蜂鸣器报警的时长或者关闭蜂鸣器。适应不同的应用场景。另外可以设置温度的显示单位为摄氏度或者华氏度，适应不同的应用场景和使用习惯。</span></span></p>
