要求
===

[](#要求-)

PHP>=5.4
composer
cron

安装
===

[](#安装-)

执行`composer create-project -s dev peinhu/pm25alert`。

在`config/notification.php`中设置通知方式的相关参数，在`config/subscribers.php`中设置订阅者的相关信息。

执行`crontab -e`，在末尾增加一行`* * * * * /usr/bin/php /path-to-project/index > /dev/null 2>&1`，注意`/usr/bin/php`请以实际为准，`path-to-project`替换成项目文件夹的路径。

说明
===

[](#说明-)

按PM2.5浓度而非AQI（空气质量指数）进行计算分级，分级标准参照中国/美国标准，结果仅反映PM2.5的污染情况。

默认使用pm25.in提供的api，也可换用其它api，创建一个新的DataProvider并将数据整理成标准数据格式即可。

默认使用email进行通知，也可自行扩展其它通知服务。

发送记录和错误日志位于`log/notification.log`。
