GUVA-12SD UV Sensor Module

The GUVA-12SD is a UV (Ultraviolet) Light Sensor module used to detect UV light intensity, particularly in the UVA range (320-400 nm). It is designed for applications like UV index measurement, UV exposure detection, and other UV-based sensing tasks. The sensor detects UVA light using a photodiode that generates a small current when exposed to light in the 320-400 nm range. The intensity of the UV light determines the amount of current produced by the photodiode.

This current is converted into an analog voltage. The voltage output is linear, meaning the analog signal directly corresponds to the UV light intensity.

The sensor’s output can be read by an analog input pin on a microcontroller, such as an Arduino. Using functions like analogRead(), you can measure the UV intensity in real-time and use the data for monitoring or UV index calculations.

GUVA 12SD UV Sensor Module Specifications:

• • Operating Voltage: 3.3V to 5Vdc
  • Spectral Range: 320 nm to 400 nm (UVA region)
  • Peak Sensitivity Wavelength: 360 nm
  • Sensor Type: UV Photodiode
  • Connection: 3 pins (VCC, GND, SIO/OUT)

 Key Features:

• UV Sensitivity: Sensitive to UVA light in the 320-400 nm range.
• Analog Output: Produces a linear analog voltage proportional to UV light intensity.
• Low Power Consumption: Ideal for battery-powered devices.
• Easy to Use: Compatible with Arduino and other microcontroller platforms.

How It Works:

• The Guva12sd sensor converts UV light intensity into an analog voltage that can be read by an analog input pin on a microcontroller.
• The output voltage increases with the intensity of the UV light detected, allowing you to measure UV exposure in real time.

It’s commonly used in applications like UV index monitoring, sun exposure tracking, and environmental sensing systems.
