Using this extension

点击齿轮，然后点击拓展，输入URL https://github.com/cdjq/pxt-DFRobot_UVIndex240370Sensor 添加拓展。

Using the extension

这个拓展用到了紫外线传感器来获取数据。请确保 micro:bit 与传感器正确连接。

Read Number

voltage = DFRobot_UVIndex240370Sensor.readUv(DFRobot_UVIndex240370Sensor.eDataType.OriginalData)
index = DFRobot_UVIndex240370Sensor.readUv(DFRobot_UVIndex240370Sensor.eDataType.IndexData)
level = DFRobot_UVIndex240370Sensor.readUv(DFRobot_UVIndex240370Sensor.eDataType.RiskLevelData)

Testing

1. 编写测试程序

let voltage = 0
let index = 0
let level = 0
basic.forever(function () {
    voltage = DFRobot_UVIndex240370Sensor.readUv(DFRobot_UVIndex240370Sensor.eDataType.OriginalData)
    serial.writeNumber(voltage)
    index = DFRobot_UVIndex240370Sensor.readUv(DFRobot_UVIndex240370Sensor.eDataType.IndexData)
    serial.writeNumber(index)
    level = DFRobot_UVIndex240370Sensor.readUv(DFRobot_UVIndex240370Sensor.eDataType.RiskLevelData)
    serial.writeNumber(level)
})

2. 下载到micro:bit中
3. micro:bit通过拓展板与传感器相连，同时mocro:bit通过USB与电脑相连
4. 把传感器放在有阳光或其他发出紫外线的区域，观察串口数据打印
