Solar UV Radiation Meter🌤

Frequent or prolonged exposure to high levels of solar 🌞 ultra-violet ( UV ) radiation can damage the human skin.

The SpacerLabs solar 'UV Radiation Meter' ( abbreviated UVRM ) provides a way to measure the radiation and display the result as the UV Index and UV Level. Informed decisions about appropriate precautions can then be taken if necessary. 😎🤠

The UVRM is based on the Silicon Labs SI1145 'UV Index sensor', together with a 32bit micro-controller, blue 0.96" 128x64px OLED display module and power management system. The UVRM is powered by an internal 3.7V rechargeable Lithium battery, which can be charged in-situ via the micro USB connector. A custom 3-D printed blue & white hand-held enclosure gives the UVRM a smart appearance.

UV Index ( zero to 11+ with a resolution of 0.01 ), and UV Level are displayed according to the W.H.O definitions; Low, Moderate, High, Very High & Extreme. The SI1145 also derives a "Visible Light Index" ( VIS ) and an "Infra-Red Index" ( IR ). These indices are not displayed directly by the current versions of the UVRM.

Two main options have been developed allowing the UVRM to be used as a stand-alone device when extended battery life is important or the option of wireless connectivity using BluetoothⓇ.

SpacerLabs has developed a custom App called  "Light_Meter" to connect to the UVRM using BluetoothⓇ communications.

Using one of the BluetoothⓇ versions of the UVRM with a paired and connected mobile device running the App makes it easier to view the data in some outdoor situations 🌞. The VIS and IR indices are also exposed.
