Consistent Output
Been logging data for three weeks straight. The voltage output remains consistent and doesn't drift much even with temperature changes.

Good accuracy for the price
Compared readings with a professional handheld meter and they were quite close. Not lab-grade precision, but excellent for DIY weather stations.

Robust and Easy to Integrate
Bought ten of these for our workshop. Students found them very easy to wire up using the Grove interface. No drivers needed, just plug and play.

Great starter sensor
My first UV sensor. Documentation could be slightly more detailed for beginners, but online forums helped me get it running in an hour.

Perfect for Arduino Projects
This sensor works flawlessly with my Arduino Uno. The analog output is stable and easy to read. Great for building a simple UV index monitor for my garden.

Reliable Sunlight Detection
Using this to automate shading curtains in my greenhouse. It triggers exactly when the UV levels get too high for my plants. Very satisfied.
Q: Is a separate library required for Raspberry Pi?
A: Since the output is analog, you cannot connect it directly to a standard Raspberry Pi GPIO. You will need an external ADC chip like the MCP3008.
Q: Does this module output digital or analog signals?
A: The UVM-30A outputs an analog voltage signal proportional to the UV intensity. You will need an ADC (like on an Arduino) to read the value.
Q: Can this sensor detect UVC light from germicidal lamps?
A: The detection range is 200-370nm, which covers UVA, UVB, and some UVC. However, it is primarily calibrated for solar UV index monitoring.
Q: What is the maximum voltage this sensor can handle?
A: The operating voltage range is 3.0V to 5.0V DC. Do not exceed 5V as it may damage the internal circuitry.
Q: How do I calibrate this sensor for accurate lux readings?
A: This sensor measures UV intensity, not visible light (Lux). For UV, you can map the 0-1023 ADC value to a UV Index scale using the formula provided in the datasheet.
