DIYables GUVA-S12SD UV Sensor Module 240-370nm 130 Degree, Presoldered
Click to zoom
Quick Overview
This DIYables GUVA-S12SD UV sensor module detects ultraviolet light across a 240nm to 370nm wavelength range, making it well suited for measuring solar intensity and sunlight exposure. Its 130 degree large angle detection area captures UV signal from a wide field of view rather than a narrow, direct-line sensing spot.
The module operates on a 2.5V to 5V supply with low power consumption and a good linear response, delivering high sensitivity and long-term stability for consistent readings. The compact 11mm x 27mm board comes presoldered with header pins for immediate breadboard use with Arduino, ESP32, and other 3.3V/5V microcontrollers.
This listing includes 2 GUVA-S12SD UV sensor modules, ideal for UV testers, UV watches, outdoor sports equipment, solar intensity monitoring, and other Arduino-based UV detection projects.
