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 monitor for the amount of UV light and is simple to connect to any microcontroller. I recently noticed that some sellers had little modules for this sensor at a reasonable price so decided to purchase one.
The module, with a typical UV detection wavelength of 2400 – 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.
Small size: 11mm × 27mm
2. Low power consumption: supply voltage 2.5V ~ 5V, the working current is microampere level
3. Good linearity
4. High sensitivity
5. High stability
6. Detection range: 240nm-370nm
7. Large angle: 130 degrees
8. Schottky type of photodiode, suitable for photoelectric mode
Ultraviolet testers, UV watches, outdoor sports equipment, mobile phones and other mobile phones
This product, in particular, is the only one in the world that can be used in the field of mobile phones. And has a direct response to the ultraviolet index (UV INDEX) of the linear current.
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)
