The GUVA-S12SD UV Sensor chip is suitable for detecting the UV radiation in sunlight. It can be used in any application where you want to monitor for the amount of UV light and is simple to connect to any microcontroller.
Arduino and GUVA-S12SD UV Sensor:
The module, with a typical UV detection wavelength of 200 – 370nm, outputs a calibrated analog voltage which varies with the UV light intensity so basically all you need to do is connect this to an ADC input and read in the value.
Connection:
The connections are straightforward and described below, I used 3.3v from my Arduino. This was mainly for compatibility with other development boards but the module works with 5v.
1. GND: 0V (Ground)
2. VCC: 3.3V to 5.5V
3. OUT: 0V to 1V ( 0 to 10 UV Index)
Package Includes:
1 x CJMCU-GUVA-S12SD Sunlight Ultraviolet Ray Intensity UV Sensor
