0-50cm F3 Infrared Tube Photoelectric Switch IR Beam Sensor for Arduino, ESP32 & Robotics
The 0-50cm F3 Infrared Tube Photoelectric Switch IR Beam Sensor is a compact infrared obstacle detection sensor designed for Arduino, ESP32, Raspberry Pi, STM32, and other microcontroller projects. It uses an infrared LED transmitter and phototransistor receiver to detect nearby objects within a sensing range of approximately 0 to 50 cm.
This IR beam sensor is widely used in robotics, smart automation, object counting, line detection, industrial automation, security systems, automatic doors, and DIY electronics projects. Its small size, fast response, low power consumption, and easy interfacing make it an excellent choice for students, engineers, hobbyists, and makers in Bangladesh.
The F3 Infrared Tube Photoelectric Switch Sensor is an optical proximity sensor that detects objects by transmitting infrared light and receiving reflected signals. When an object enters the sensing area, the reflected IR light changes, allowing the sensor circuit to generate a detection signal.
With a detection distance of up to 50 cm (depending on object color, size, and ambient lighting), this sensor provides stable and reliable performance for a wide range of embedded systems and automation projects.
Whether you are building an autonomous robot, smart dustbin, automatic hand sanitizer, line follower robot, object counter, or industrial automation project, this sensor offers dependable performance at an affordable price.
