硅太阳UV传感器手链检查太阳紫外线辐射的低，中，高或非常高/极端水平;

硅太阳紫外线传感器手环可以根据太阳紫外线辐射，更高的太阳紫外线辐射，更深的颜色变化，比较颜色变化与4种标准颜色（低，中，高，非常高/极端）周围和你可以看到太阳紫外辐射的低，中等，高或非常高/极端水平;

告诉你什么时候是最好的时候使用太阳能充电器或类似的太阳能设备有效：

低：UVI 1-2，太阳能设备不能使用;

中等：UVI 3-5，太阳能设备可以使用，但效率低;

高：UVI 6-7，可以使用太阳能设备，但效率为MID;

非常高/极端：UVI 8-11 +，太阳能设备可以使用，效率高。

告诉你UVIndex和SPF的防晒霜你应该应用：

低：UVI：1-2，SPF <5，不需要防晒;

中度：UVI：3-5，SPF <10，建议防晒;

高：UVI：6-7，SPF <15，需要防晒

非常高/极端：UVI：8-11 +，SPF <30，避免暴露在阳光下;

它也可以是荧光和发光在黑暗的夜晚，非常有趣的人在户外活动。

Silicon Solar UV Sensor bracelet check low, moderate, high or very high/extreme level of Solar UV radiation;

The Silicon Solar UV Sensor bracelet can change colors according to Solar UV radiation, higher the Solar UV radiation, deeper the color change, compare the color change to the 4 standard colors (low, moderate, high, very high/extreme) around and you can see low, moderate, high or very high/extreme level of Solar UV radiation;

Tell you when is the best time to use solar charger or similar solar equipment effeciently:

Low: UVI 1-2, Solar energy equipment can not be used;

Moderate: UVI 3-5, Solar energy equipment can be used but the efficiency is low;

High: UVI 6-7, Solar energy equipment can be used but the efficiency is MID;

Very High/Extreme: UVI 8-11+, Solar energy equipment can be used and the efficiency is high.

Tell you UVIndex and SPF of sunscreen you should apply:

Low: UVI: 1-2, SPF ﹤5, sun protection not necessary;

Moderate: UVI: 3-5, SPF ﹤10, sun protection recommended;

High: UVI: 6-7, SPF﹤ 15, sun protection necessary

Very high/Extreme: UVI: 8-11+, SPF﹤30, , avoid exposure to the sun;

It can also be fluorescent and glow in the dark night, very interesting for people in outdoor activities.
