Description：
This is a UV-tested sensor that includes GUVA-S12SD, which can be widely used for UV index detection of smart wearable devices, such as watches with UV index detection, smartphones with UV index detection, outdoor devices with UV index detection, etc. It can also be used to monitor UV intensity, UV flame detectors and UV disinfection and so on.

The sensor is compatible with various microcontroller control boards, such as the Arduino series of microcontrollers. When using, we provide a method to use this sensor with the Arduino series of microcontrollers. Input the sensor signal end to the analog port of the Arduino series MCU, and sense the change of UV content, and display the corresponding analog value on the serial monitor.

The sensor comes with a 2.54mm anti-reverse plug white terminal. When in use, we can connect to the MCU with DuPont cable. To facilitate wiring, we specially  designed an expansion board that is fully compatible with this sensor and the Arduino UNO R3 microcontroller. We only need to stack the expansion board to the UNO R3 MCU, and use a 3P double-head XH2.54 plug wire (anti-reverse) to connect to the expansion board, which is simple and convenient.

At the same time, the sensor comes with 4 3mm diameter positioning holes, which allows you to fix the sensor to other devices.
