KY-010 Broken Light Blocking Sensor

The KY-010 Broken Light Blocking Sensor uses infrared beam interruption to detect objects passing through its compact U-shaped detector frame, providing a reliable method for precise motion and presence sensing.

Key features include:

• Infrared light blocking detection for consistent object sensing.
• Compact U-shaped form factor suited for installations in confined or guided paths.
• Fast response behavior that supports real-time detection tasks.
• Broad compatibility with common microcontroller platforms for straightforward integration.
• Stable operation across a range of ambient light conditions.

Operation is based on an infrared emitter and a phototransistor detector arranged to form a precise light barrier; when an object interrupts the beam, the sensor registers the change and outputs a clear detection signal. This beam interruption method reduces false triggers that can affect traditional reflective optical sensors and offers improved repeatability for applications that require reliable object presence confirmation.

The KY-010 is well suited for automation, robotics, conveyor monitoring, position sensing, and hobbyist projects where a non-contact, interrupt-style detector is required. Its simple interface and compact geometry allow it to be mounted in guided slots or frames, enabling consistent detection of passing items or moving parts. The design emphasizes dependable performance and ease of integration into systems that need prompt, unambiguous detection of beam interruptions.
