This infrared proximity sensor utilizes a paired IR transmitter and receiver to detect obstacles by measuring reflected infrared light. The integrated LM393 voltage comparator processes the received signal, providing a robust digital output that transitions to low logic level upon detection, making it ideal for real-time obstacle avoidance systems.
Designed for indoor use to minimize interference from ambient sunlight, the module includes a sensitivity adjustment potentiometer to fine-tune the effective sensing distance. Its compact form factor and standard 3mm mounting holes facilitate easy integration into robotic platforms, automated guides, and security applications.
