Description :

-The gray scale sensor measures the intensity of light from black to white
-It is composed of a photocell (light-controlled variable resistor) and an integrated white LED on board
-The connected LED allows for reflective feedback and analysis of gray scale light ranges
-Can be used for automatic lamps, simple data transmission (Morse code with a flashlight), and line following (tracking) sensors
-Improved quality connector increases sensor lifespan and better voltage range for ease of use.

-Features:

•Wide voltage range from 3.3V to 5V
•Standard assembling struct (two 3mm holes with multiple of 5 cm as interval)
•Easily recognitive interfaces of sensors ("A" for analog and "D" for digital)
•Icons to simply illustrate sensor function
•High quality connector
•Immersion gold surface
-Specifications:
•Supply Voltage: 3.3V to 5V
•Interface: Analog
•Size:22x30mm (0.87 x 1.18 in)
