This module is suitable for various electronics platforms like Arduino, Raspberry Pi, ESP32 and others.

KY-010 SPECIFICATIONS

This module consists of an optical emitter/detector and 3 male header pins on the front. On the back there are two resistors of 1kΩ and 33Ω.

The sensor uses a beam of light between the emitter and detector to check if the path between both is being blocked by an opaque object.

Operating Voltage 3.3V ~ 5V
Board Dimensions  18.5mm x 15mm [0.728in x 0.591in]

Connect the power line (middle) and ground (left) to +5V and GND respectively. Connect signal (S) to pin 3 on the Arduino.
