The Red Laser Transmitter Module is a compact laser diode module designed for alignment, detection, and basic optical projects. It operates from a 5 V DC power source, making it directly compatible with Arduino and other microcontroller platforms. The module emits a visible red laser at a wavelength of 650 nm with a power output of 5 mW, ensuring stable and consistent performance. It is commonly used in theft detection systems, laser pointers, and educational experiments involving light sensing and beam interruption.
