Description
Product Overview
The KAIOULU Infrared Break Beam Sensor Switch is a compact, high‑performance photoelectric sensor designed for hobbyists, engineers, and industrial users. Each package contains three identical sensor units, each built with a durable plastic enclosure and robust metal pins that provide a secure, low‑resistance connection to your circuit board or breadboard. The sensor operates on a standard 5 V DC supply, making it compatible with virtually any microcontroller platform, including Arduino, Raspberry Pi, and ESP series boards.
At the heart of each module is an infrared transmitter and receiver pair that creates an invisible beam across a 30 cm detection zone. When an object interrupts this beam, the sensor instantly changes its output state, allowing you to trigger alarms, control motors, or log events with millisecond‑level responsiveness. Integrated voltage regulation ensures stable operation even when supplied from fluctuating power sources, while dual indicator LEDs provide immediate visual feedback for power status and beam interruption.
Key specifications include a package size of 1.97 × 1.18 × 0.39 inches, a weight of 1.76 oz, and a best‑seller rank of #60 in the Photoelectric Sensors category on major e‑commerce platforms. The sensor’s lightweight design enables installation in confined spaces such as robotic arms, conveyor belts, and custom enclosures without compromising performance.
Usage
These infrared break beam sensors excel in a wide variety of applications. In DIY electronics projects, they can be used to create automatic door openers, object counters, and line‑following robots. For automation engineers, the sensors provide reliable object detection for conveyor systems, packaging lines, and safety interlocks, ensuring that machinery stops or starts precisely when needed.
Because the sensor operates on a 5 V DC supply, it integrates seamlessly with battery‑powered portable devices, solar‑charged stations, and USB‑powered development kits. The built‑in LEDs make troubleshooting straightforward: a steady green LED indicates power is present, while a flashing red LED signals that the infrared beam has been broken.
Industrial users appreciate the sensor’s resistance to ambient light interference, thanks to its infrared wavelength selection and narrow beam profile. This makes it suitable for environments with fluctuating lighting conditions, such as warehouses, factories, and outdoor installations where sunlight or artificial lighting could otherwise cause false triggers.

FAQ
What is the maximum detection distance of the sensor?
The sensor can reliably detect objects up to 30 cm away under normal indoor lighting conditions. Performance may vary slightly with ambient infrared sources.
Can the sensor be powered by a battery?
Yes, the sensor operates on a 5 V DC supply, which can be provided by a standard AA battery pack, a USB power bank, or any regulated 5 V source.
Is the infrared beam visible to the naked eye?
No, the beam operates at an infrared wavelength that is invisible to the human eye, making it ideal for discreet applications and preventing visual distraction.
How do I connect the sensor to a microcontroller?
Connect the VCC pin to a 5 V source, the GND pin to ground, and the OUT pin to a digital input on your microcontroller. The output goes low when the beam is broken.
What safety precautions should I take when installing the sensor?
Ensure the sensor is mounted securely to avoid movement that could misalign the transmitter and receiver. Keep the sensor away from strong infrared sources such as remote controls or heat lamps to prevent false triggering.
With its blend of precision engineering, user‑friendly features, and robust support, the KAIOULU Infrared Break Beam Sensor Switch is an ideal choice for anyone looking to add reliable, non‑contact detection to their electronic or industrial projects.
