Description

GY-31 Color Sensor Module is made using IC TCS3200, a programmable color light to a frequency converter. It has configurable silicon photodiodes and a current to frequency converter in a single monolithic CMOS Integrated Circuit. Its output is a square wave having a 50% duty cycle with frequency directly proportional to irradiance (light intensity). This module can be directly interfaced with Microcontrollers, Arduino Boards, Raspberry Pi, etc.

Note: This Product is available in two different variants (GY-31 and HW-531) with the same working we will ship it randomly.

Features:

  1. High-Resolution Conversion of Light Intensity to Frequency
  2. Programmable Color and Full-Scale Output Frequency
  3. Power Down Feature
  4. Stable Temperature Coefficient
  5. Can be directly interfaced with a Microcontroller

Package Includes:

1 x GY-31 TCS3200 Color Sensor Module
