FAQ Section
FAQ Section
Q: How do I connect the UVM-30A to my Arduino?
A: Connection is simple. Connect the '+' pin to your Arduino's 3.3V or 5V output, the '-' pin to Ground (GND), and the 'out' pin to any analog input pin (e.g., A0). You can then use the analogRead() function to capture the UV data.
Q: Is this sensor module waterproof for outdoor weather stations?
A: The actual UV sensor component features a patented waterproof and dustproof polymer structure, making it highly resilient. However, the exposed PCB and header pins are not waterproof. For permanent outdoor use, we recommend housing the PCB in a weatherproof enclosure while leaving the white sensor window exposed to the sky.
Q: Do I need a special library to read the UV index?
A: No special library is required. Because the module provides a linear analog output (typically 0.1V = UVI 1, 0.2V = UVI 2, up to 1.0V = UVI 10+), you can calculate the UV index using basic multiplication in your code.
