GUVA-S12SD UV sensor

MCU-GUVA-S12SD UV intensity sensor for sunlight

Specification:

Size: 11 mm x 27 mm
Low power consumption - supply voltage 2.5 V ~ 5 V, operating current is only a few microamperes
High sensitivity
High stability
Detection range: 240 nm to 370 nm
Large angle: 130 degrees
The Schottky photodiode for photoelectric mode

Easy to use with Arduino. The strength of the UV radiation is output in the form of a voltage. This voltage is simply recorded and evaluated at the analog port on the Arduino microcontroller.
