Easy to integrate
Documentation could be slightly better, but standard libraries work well with it. The signal is clean and easy to read via ADC.

Robust build quality
Been using this outside in a protected casing for three months now. No degradation in performance despite varying temperatures. Very satisfied.

Reliable and compact
Bought five of these for a student workshop. All units performed consistently. The form factor is small enough to fit into tight enclosures.

Perfect for my weather station project
This sensor works flawlessly with my Arduino setup. The analog output is stable and reacts quickly to changes in sunlight intensity. Great value for the price.

Good sensitivity, needs calibration
The module is very sensitive to UV rays. I had to write a small calibration script to map the voltage to actual UV index values, but once done, it works great for monitoring plant exposure.

Excellent detection range
I use this to track peak sun hours for my solar panels. It detects even slight cloud cover changes effectively. Highly recommended for DIY solar projects.
Q: Does it detect UVA, UVB, or both?
A: The spectral response covers a broad range typically including both UVA and UVB wavelengths (approx. 200nm-370nm), suitable for general sunlight intensity monitoring.
Q: Does this sensor output digital or analog signals?
A: The S12SD module outputs an analog voltage signal proportional to the detected UV intensity. You will need an ADC (Analog-to-Digital Converter) to read it with a microcontroller.
Q: What is the maximum distance for accurate detection?
A: This is a proximity sensor designed to measure ambient UV light falling directly on the sensor surface. It does not detect UV sources from a distance like a radar; it measures incident light intensity.
Q: Can this be used directly with a 5V Arduino Uno?
A: Yes, the sensor operates comfortably within the 3.3V to 5V range, making it fully compatible with the 5V logic of the Arduino Uno.
Q: Is the sensor waterproof?
A: The module itself is not waterproof. For outdoor use, please house it in a weatherproof enclosure with a UV-transparent window.
