Description
This photo interrupter sensor is a reliable speed-measuring module designed for smart robots, DIY vehicles, and rotary encoder projects. It is an ideal component for students, hobbyists, and makers looking to implement precise speed tracking and position sensing in their builds.
Optical beam interruption
The sensor detects obstacles passing through its slot by interrupting an optical beam, triggering a change in the output signal. This design allows for precise, non-contact sensing of rotating components.
Rotational speed tracking
When paired with a slotted encoder disc, this module functions as a highly effective tachometer for mobile robot wheels. It translates physical rotation into digital pulses that your microcontroller can count to calculate speed.
Robust digital output
The module delivers a clean digital signal to simplify programming and connection to development boards. This ensures reliable pulse detection even in busy educational robotics environments.
Convenient mounting options
Equipped with pre-drilled mounting holes, the board can be securely fastened to your robot chassis or custom bracket. Its compact form factor makes it easy to position near motors and axles.
