“UV index meter using GUVA-S12SD.
In this project I’ll show you how to make a UV index meter which can show the UV index and the UV state using GUVA-S12SD UV sensor.
About the Sensor
GUVA-S12SD is a Gallium Nitride Based Schottky-type Photodiode. It has a typical UV detection wavelength of 240-370nm(which covers UVB and most of UVA spectrum). It outputs a calibrated analog voltage which varies with the UV light intensity. So, we can read the analog value via Arduino ADC.”
