S12SD Sunlight Ultraviolet Ray Intensity UV Sensor

Gallium Nitride (GaN) UV Photodiode Telemetry: Utilizes a highly sensitive GaN-based S12SD photodiode to directly quantify solar ultraviolet radiation levels (240 nm - 370 nm).

UVA & UVB Solar Spectrum Coverage: Broad spectral responsiveness allows accurate measurement of both UVA (315 nm - 400 nm) and UVB (280 nm - 315 nm) radiation components.

Onboard Signal Amplification Circuitry: Outfitted with an operational amplifier that converts micro-amp photodiode currents into a stable, low-noise analog output voltage.

Seamless Microcontroller Compatibility: Works natively across 3.3V and 5V logic levels for quick, plug-and-play ADC readings on Arduino, ESP32, and Raspberry Pi.

Compact Low-Power Breakout Design: Ultra-small PCB footprint with low current draw, making it ideal for battery-operated weather stations and portable outdoor gear.

Housing & Board Material: Double-sided FR-4 glass-epoxy PCB with a sealed S12SD GaN UV photodiode package and surface-mount components.

Technical Specifications:

Operating Voltage: 2.7V - 5.5V DC.

Spectral Response Range: 240 nm - 370 nm (UVA/UVB spectrum).

Output Signal: Analog Voltage Output.

Product Weight: 0.05 kg.

Color: Purple PCB with Gold Contact Terminals.

Usage Advice: Connect VCC (2.7V-5.5V), GND, and SIG to an analog ADC input pin; orient the sensing photodiode directly toward the light source without blocking glass or heavy acrylic.

Maintenance: Keep the optical surface of the photodiode clean and free from dust or grease; gently wipe with a dry microfiber cloth if dirty.

Essential Outdoor Environmental Transducer: Position as a top choice for solar UV index monitoring, weather station telemetry nodes, outdoor exposure safety wearables, and greenhouse crop tracking.

Highlight Solid-State GaN Sensitivity: Emphasize how Gallium Nitride photodiode technology offers superior UV selectivity and durability compared to standard silicon photodiodes under long-term sunlight exposure.

Recommended Cross-Sell Add-ons: Pair with ACEBOTT UV Sensor Module Easy-Plug for ESP32/Arduino, GY-ML8511 UV sensor module, OPT3001 Ambient Light Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
