Full Product Description

Precision UV Detection for Your Next Electronics Project

Whether you are building a smart agriculture system or an automated weather station, understanding environmental sunlight is crucial. The GUVA-S12SD Sunlight UV Intensity Sensor is designed to provide highly accurate and stable ultraviolet light measurements. By utilizing an advanced Schottky-type photosensitive diode, this module translates ambient UV radiation into a clear, readable analog voltage signal that your microcontroller can easily interpret.

 

Covering the Essential UV Spectrum

Not all UV sensors are created equal. The GUVA-S12SD boasts a wide detection range of 240nm to 370nm, allowing it to effectively capture both UVB and UVA rays. Combined with a broad 130-degree viewing angle, it ensures comprehensive light absorption, reducing blind spots in your data collection and giving you a true representation of the environmental UV index.

 

Seamless Integration and Low Power Consumption

Engineered for modern DIY and professional applications, this sensor operates efficiently within a 2.5V to 5V power supply range. Its microamp-level working current makes it incredibly power-efficient, ensuring your battery-operated remote nodes and IoT devices run longer without needing frequent maintenance. With its compact 11mm x 27mm footprint, it easily fits into tight enclosures and complex circuit layouts.

FAQ Section

Q: Which microcontrollers are compatible with the GUVA-S12SD sensor?
A: Because it outputs a standard analog voltage signal, it is fully compatible with almost any microcontroller equipped with an ADC (Analog-to-Digital Converter), including Arduino UNO, ESP32, ESP8266, and Raspberry Pi (with an external ADC module).

Q: Can I use this to measure the exact UV Index?
A: Yes. The sensor provides a linear output voltage that correlates directly with the UV Index. By mapping the analog voltage readings in your code (typically 0-1V mapping to UV Index 0-10), you can estimate the current UV Index accurately.

Q: Is this sensor waterproof for outdoor weather stations?
A: The bare PCB module is not waterproof. For outdoor applications, you must install the sensor inside a weatherproof enclosure with a UV-transparent window (like quartz glass or specific clear acrylics) to protect the components while allowing UV light to reach the diode.
