The ELECROW Crowtail – UV Sensor (GUVA-S12SD) is an analog sensor module designed to detect ultraviolet (UV) light intensity, particularly in the UVA and UVB ranges. Utilizing the GUVA-S12SD sensor, it converts UV light into a measurable analog voltage, which can be read by microcontrollers like Arduino or ESP32. The sensor operates over a wide wavelength range of 200nm to 370nm, making it suitable for applications such as UV index monitoring, solar radiation measurement, and environmental sensing. With an operating voltage range of 3.3V to 5V, it is compatible with various development platforms. The module is designed for easy integration into projects, offering a straightforward interface for detecting UV light levels. Its compact size and low power consumption make it ideal for portable and battery-powered applications. Whether you're building a weather station, a wearable UV monitor, or conducting environmental research, this sensor provides a reliable solution for UV light detection.
