KY-010 Photo Interrupter Speed Measuring Sensor Module is a compact optical sensor module designed for Arduino and other microcontroller-based projects. This module uses an infrared light emitter and receiver system to detect interruptions in the light beam. When an opaque object blocks the light path between the emitter and detector, the module generates a digital signal that can be used for speed measurement, object detection, rotation counting, and automation applications.

The KY-010 optical interrupter sensor module is widely used in robotics, motor speed monitoring, encoder systems, automation projects, and DIY electronics. Its simple digital output design makes it easy to connect with Arduino, Raspberry Pi, and other development boards for real-time detection and measurement.

How It Works:

• The module contains an infrared light emitter and infrared detector positioned in a U-shaped gap.

• The emitter continuously sends an infrared beam toward the receiver.

• When an object enters the gap and blocks the beam, the sensor detects the interruption.

• The module outputs a digital signal that can be processed by a microcontroller.

• By counting interruptions over time, the speed or rotation rate of an object can be measured.

Applications:

• Motor speed measurement

• Rotary encoder projects

• Wheel rotation detection

• RPM measurement systems

• Object detection systems

• Line and position sensing projects

• Robotics projects

• Arduino automation projects

• DIY electronic experiments

• Industrial counting systems

• Mechanical movement monitoring

• Smart device prototypes

How to Use:

• Connect the module to a microcontroller such as Arduino.

• Connect VCC to the power supply, GND to ground, and signal pin to a digital input pin.

• Place a rotating disc, fan blade, or moving object inside the sensor gap.

• Monitor the digital output signal when the light beam is interrupted.

• Use programming logic to count pulses and calculate speed or rotation.

Product Instructions:

• Ensure the object being detected can block the infrared light beam.

• Keep the sensor gap clean for accurate detection.

• Avoid strong external light interference for better performance.

• Use the correct voltage supply according to the controller requirements.

• Handle the sensor carefully to prevent damage to the infrared components.
