It's a logo of Netatmo Rain Module reduced to a small module. The module is shaped like the top of a flash light without the stem of the flash light.
This Netatmo Rain Module icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,900 icons, all in the same style and quality.
