AI_ES6环境检测器

封装了一个方法用来获取AI_ES6的环境检测数据

1.实例化AI_ES6，参数1是接口连接中控的端口，参数2是定时查询环境数据的时间间隔

2. 设置设备ID，必须调用此方法设置设备ID，接收到数据将对比设置的ID，相同才处理。

3. 注册回调监听，定时触发回调，传入当前环境信息

var AIES6 = new AI_ES6(COM1,10); //设备接COM1，每10S查询一次
AIES6.setID(2); //设备出厂默认ID是3，所以在接上设备必须调用此方法设置ID，否则不触发回调
AIES6.on(function(data) {
console.log(data);
}

回调出入的对象格式如下
number为当前环境值
name 为当前检测对象的名称
unit 为当前环境值的单位
level 为当前环境值相较国标的等级
level 取值在 HCHO 和 TVOC 中可能为 "正常、轻微、严重、危险"四种情况
level 取值在 PM25 和 AQI 中可能为 "优、良、轻度污染、中度污染、重度污染、严重污染"五种情况
下面 json 中 unit 、 level 键值为""的，将永久为""

{
HCHO: { number: 0.028, name: '甲醛', unit: 'mg/m3', level: '正常' },
TVOC: { number: 0.192, name: '有机挥发气体', unit: 'mg/m3', level: '正常' },
PM25: { number: 4, name: 'PM2.5', unit: 'ug/m3', level: '优' },
TEMP: { number: 32.8, name: '温度', unit: '℃', level: '' },
HUM: { number: 73, name: '湿度', unit: '%', level: '' },
AQI: { number: 5, name: '空气质量指数', unit: '', level: '优' },
PM1: { number: 3, name: 'PM1', unit: 'ug/m3', level: '' },
PM10: { number: 6, name: 'PM10', unit: 'ug/m3', level: '' },
CO2: { number: 508, name: '二氧化碳', unit: 'ppm', level: '' }
}
