## 概述

SEN0540是一个可以作为环境光获取或紫外线获取得传感器，能过使用用户库方便快捷得使用传感器。

## 库安装

使用此库前，请首先下载库文件，将其粘贴到\Arduino\libraries目录中，然后打开examples文件夹并在该文件夹中运行演示。

## 方法

```C++
  /**
   * @fn begin
   * @brief Init SEN0540 device
   * @return Return value init status
   * @retval 0  Succeed
   * @retval -1 Failed
   */
  int8_t begin(void);

  /**
   * @fn setMode
   * @brief 设置模块采集数据模式
   * @param mode 采集数据选择
   * @return NONE
   */
  void setMode(eModel_t mode);
