About this item
Adafruit GUVA-S12SD Analog UV Sensor Breakout
Extend your light-sensing capabilities with the Adafruit GUVA-S12SD Analog UV Sensor Breakout Board. This module utilizes a UV photodiode to detect ultraviolet light in the 240-370nm range, encompassing the UVB and most of the UVA spectrum. The sensor's output signal is amplified by an onboard op-amp, providing a more manageable analog voltage output suitable for microcontroller projects.
Key Features
- Detects 240-370nm UV light (UVB and most UVA)
- Analog voltage output for simple integration
- Amplified signal for easier reading
- Tabletop mounting design
- Compatible with Arduino, Raspberry Pi, and other microcontrollers
- Requires 2.7-5.5VDC power
Specifications
- Brand: Adafruit
- Part Number: GUVA-S12SD
- UV Spectrum Detected: 240-370nm
- Output Voltage Formula: Vo = 4.3 x Diode-Current (uA)
- UV Index Conversion: UV Index = Output Voltage / 0.1V
- Operating Voltage: 2.7-5.5VDC
Usage Notes
Connect V+ to your power supply (2.7-5.5VDC) and GND to power ground. Read the analog signal from the OUT pin. For accurate readings, be aware that UV LEDs operating at 400nm are outside this sensor's detection range. UV tanning lamps or 'lizard lamps' are recommended for testing.
