Good sensitivity, needs calibration
The sensor picks up changes in sunlight intensity very quickly. I had to do some manual calibration to get exact readings, but once set up, it performs reliably.

Works well with ESP32
Connected directly to the ADC pin on my ESP32. Readings are smooth after applying a simple moving average filter in code. No issues with noise so far.

Perfect for my weather station project
This sensor module works flawlessly with my Arduino setup. The analog output is stable and correlates well with local UV index reports. Very easy to integrate.

Compact and efficient
Small form factor makes it easy to mount inside my custom enclosure. The voltage output scales linearly with UV exposure as expected. Highly recommended.

Great value for educational kits
We bought ten of these for our student workshops. They are robust enough for beginners and provide consistent data for science experiments regarding solar radiation.

Exceeded expectations
I was worried about the accuracy at this price point, but it compares surprisingly well to my dedicated handheld UV meter. Fast shipping too!
Q: Can this sensor detect UVC light from germicidal lamps?
A: The GUVA-S12SD chip is primarily sensitive to UVA and UVB ranges (200nm-370nm). While it may show some response to UVC, it is not specifically calibrated for accurate UVC measurement.
Q: Does this module output digital or analog signals?
A: This module provides an analog voltage output that varies proportionally with the detected UV intensity. You will need an ADC (Analog-to-Digital Converter) to read the data with a microcontroller.
Q: What is the maximum voltage I can supply to this module?
A: The operating voltage range is 3.3V to 5V DC. Please do not exceed 5V as it may damage the sensor chip.
Q: Is there a library available for Arduino?
A: Since it outputs a simple analog voltage, no specific library is required. You can read the value using the standard analogRead() function and map it to UV index values based on your calibration.
Q: How do I protect the sensor from rain if used outdoors?
A: The module itself is not waterproof. For outdoor use, you must house it in a waterproof enclosure with a transparent window that allows UV light to pass through, such as specific quartz or specialized UV-transparent plastics.
