GUVA-S12SD Analog UV Light Sensor Module (240–370 nm)

Accurately measure ultraviolet radiation for your next environmental or wearable project with the GUVA-S12SD UV Light Sensor Module. Featuring a highly sensitive Schottky-type photodiode, this sensor detects UV radiation in the 240–370 nm spectrum, effectively capturing both UVB and most of the UVA range. An onboard operational amplifier boosts the raw signal to provide a clean, linear analog voltage output that is directly proportional to the ambient UV intensity. With its wide 2.5V to 5V operating range and ultra-low power consumption, it integrates perfectly with standard Arduino, ESP32, or Raspberry Pi Pico systems, making it an excellent choice for portable, battery-powered weather stations and UV index monitors.

Key Features

• Broad UV Detection: Accurately measures the 240–370 nm wavelength range, encompassing the critical UVA and UVB spectrums.

• Linear Analog Output: Outputs an easy-to-read analog voltage (typically 0–1V) that corresponds directly to the UV index, simplifying microcontroller ADC (Analog-to-Digital Converter) integration.

• Onboard Amplification: Features an integrated operational amplifier to stabilize and boost the sensor’s microvolt output to a usable, reliable level.

• Energy Efficient: Operates at the microampere level, making it ideal for continuous environmental monitoring in battery-operated or remote IoT nodes.

• Wide Compatibility: Operates seamlessly on both 3.3V and 5V logic systems without the need for logic level shifters.
