DFROBOT 5V IR Photoelectric Switch Sensor

The DFROBOT 5V IR Photoelectric Switch is a compact and efficient break-beam sensor designed for precise motion detection. It operates on the principle of an infrared beam between an emitter and a receiver unit. The emitter projects a beam of invisible infrared light, which is detected by the receiver. When an opaque object interrupts this beam, the sensor triggers a digital output signal, enabling reliable detection of movement, counting, or timing events.

This sensor is engineered for high performance, featuring an impressive sensing range of up to 4 metres with an extremely fast and stable response time of just 0.5 milliseconds. Its small form factor allows for installation in confined or narrow spaces, making it highly versatile for a wide range of projects. Constructed with robust components, it operates reliably within an extended temperature range from -10°C to +60°C.

Key Features & Applications

• Simple Integration: Powered by a standard DC 5V supply, it is perfectly suited for use with popular microcontrollers like Arduino, Raspberry Pi, and other development boards.
• Fast Response: The 0.5ms response time makes it ideal for high-speed applications such as robotics, speed detection in competitions, and precise event timing.
• Clear Identification: The transmitter unit features a green PCB, while the receiver has a black PCB, making it easy to distinguish during setup and wiring.
• Versatile Uses: Perfect for smart robot competitions, automated systems, security projects, industrial counting, and any scenario requiring non-contact object detection.
