Description

This UV sensor module detects the intensity of incident ultraviolet radiation, a form of electromagnetic energy with wavelengths shorter than visible light. It utilizes a GUVA-S12SD photodiode, which provides a stable analog output voltage that varies linearly with changes in UV light intensity across its specified spectral range.

The module is designed for straightforward integration into environmental monitoring systems, wearable devices, and laboratory equipment. Its Grove interface simplifies wiring, requiring only a single cable connection for both power and analog signal output, compatible with common 3.3V or 5V logic systems.

Key Features

  • High-stability Schottky photodiode sensor ensures reliable, repeatable measurements.
  • Optimized spectral sensitivity across the UVA and UVB bands (200-400nm).
  • Low power consumption design suitable for battery-operated projects.
  • Grove 4-pin connector enables rapid prototyping without soldering.
  • Compact PCB footprint (20mm x 20mm) for space-constrained applications.
  • High-value build offering precise UV monitoring for educational and professional use.

Applications

  • UV index monitoring for weather stations and personal exposure meters.
  • Material curing process monitoring in industrial UV lamp systems.
  • Environmental research measuring solar UV radiation levels.
  • Integration into wearable devices for sun exposure tracking.
  • Laboratory equipment for UV light source characterization.

Frequently Asked Questions

What is the operating voltage range for this Grove UV Sensor?

The module operates on the standard Grove interface voltage, typically 3.3V or 5V DC. Always check your base shield or host controller's Grove port voltage specification before connecting. The sensor itself is low-power and compatible with both common logic levels.

How do I connect and read data from this sensor?

Connect the module to your microcontroller using the supplied Grove cable, plugging into an analog input port (e.g., A0 on an Arduino Grove Shield). The sensor outputs an analog voltage. Read this value using your platform's ADC (Analog-to-Digital Converter) and correlate the reading to UV intensity, often requiring calibration against a known source.

What does the sensor actually measure, and what is its spectral range?

This sensor measures the intensity of ultraviolet radiation. Its GUVA-S12SD photodiode is sensitive to a wide spectral range from 200 nanometers (nm) to 400 nm, covering portions of the UVC, UVB, and UVA bands. The output is proportional to the total irradiance within this range.
