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.

GUVA-S12SD UV Light Sensor Example Program

/*
   GUVA-S12SD UV Light Meter Program

  Simple program to read the analog output of the sensor and display
  the raw voltage output reading

  We are connecting sensor to analog input A0, but this can be any analog pin.

Exchange or return policy



Every item comes with a 30-day warranty. However, there are certain conditions that apply:

  1. The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).

  2. The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).

  3. The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.

Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:

  1. Provide a detailed description of the damaged item(s).
  2. Mention any tests or experiments conducted by the customer.

Please note that the store reserves the right to make the final decision regarding product replacement or refund.
