UV Light Sensor GUVA-S12SD with analog Output, 3-5V, 240-370nm

Measure the light intensity of the UVB and most of the UVA spectrum using the GUVA-S12SD board.

The analog output makes it very easy to use this sensor module. Simply supply power to VCC and GND and read the output on SIG to get the UV light intensity. Operating voltage is 2.5V-5V.
Because of the linear characteristics of the sensor it is very easy to convert the output voltage to UV index using this formula: UV index = SIG * 10 - 1
So if the output voltage on pin SIG is 0.2V, the UV index is about 1. 1.0V output voltage equals an UV index of about 9.

This breakout board can be powered with 2.5-5V and is perfect for 5V microcontroller boards like Arduino UNO as well as 3.3V boards like the Adafruit QT Py
