เซนเซอร์วัดความเข้มแสง UV MCU-GUVA-S12SD Sunlight UV Intensity Sensor

DESCRIPTION

The GUVA-S12SD UV Light Sensor Module is an analog UV light to voltage converter for measuring the intensity of UV light.

PACKAGE INCLUDES:

• GUVA-S12SD UV Light Sensor Module
• 3-pin male header

KEY FEATURES OF GUVA-S12SD UV LIGHT SENSOR MODULE:

• Detects UV light in the 240nm – 370nm range
• Analog voltage output proportional to the UV Index of UV light falling on the detector
• 3.3 and 5V compatible

The GUVA-S12SD is a true UV detector that only detects light from 240nm to 370nm which is the UV-B and most of the UV-A spectrum.  It also picks up the upper end of UV-C.

These wavelengths are used in black lights, tanning beds, reptile UV emitters, germicidal sterilizers and similar applications.  The device can be used to monitor the operation of those devices.

It can also be used to measure the UV Index which provides a scale to determine how intense the sun UV is and therefore what kind of protective measures should be taken.

The UV Index scale is published by the EPA and intended to give guidance to people on sun exposure and what protective measures to take to minimize damage from the sun.
