Later I learn that a fog detector close to the top of the lighthouse measures the amount of moisture in the air.

后来我知道，在灯塔顶部有一个用于检测空气湿度的探雾器。

I also enjoyed taking a look at the fog detector, responsible for starting the foghorn that had disturbed my peace the night before.

我还兴致勃勃地看了看探雾器，头天晚上让我不得安宁的雾号就是这个家伙弄出来的。

FOG is sensitive to temperature variety, and its temperature characteristic of detector is a worthwhile task.

光纤陀螺对温度变化比较敏感，其探测器的温度特性也是值得探索的课题。
