The Non-Modulator Laser Receiver Sensor is a compact optical detection module designed to receive direct laser signals and convert them into a digital output. It operates at 5V DC and provides a HIGH output when a laser signal is detected and a LOW output when no signal is present. The sensor is optimized for simple digital interfacing with microcontrollers and control systems. Its small PCB size makes it suitable for space-constrained designs. This module is ideal for laser detection, optical triggering, and basic communication or alignment applications.
