KY-010 FOR Optical Fracture Sensor

KY-010 Optical Fracture (Photo Interrupter) Sensor Module – Product Description The KY-010 Optical Fracture Sensor Module, also known as a Photo Interrupter Module or Light Barrier Sensor, is an infrared (IR)-based sensor designed to detect the presence or movement of objects by monitoring interruptions in an infrared light beam. The module consists of an IR emitter and an IR phototransistor positioned opposite each other, producing a digital signal whenever an object blocks the light path. Operating on 3.3V to 5V DC, the KY-010 is compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontroller platforms. Its fast response time and simple digital output make it ideal for object detection, position sensing, rotation counting, and automation applications. Features Infrared photo interrupter for accurate object detection Digital output for easy microcontroller interfacing Operating voltage: 3.3V–5V DC Fast response and reliable detection Compact and lightweight design Compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and other development boards Applications Object presence and absence detection Rotary encoder and speed measurement Position and limit switch sensing Slot or card detection systems Industrial automation and control Robotics and educational electronics projects The KY-010 Optical Fracture Sensor Module provides a simple, reliable, and cost-effective solution for non-contact object detection. Its infrared light barrier design makes it well suited for automation, motion sensing, and embedded system applications where precise interruption detection is required.
