Power Rating: Operates at 3.3V–5V DC – ensures low power consumption and stable signal output.

Type: Speed Sensor Module – uses an infrared (IR) emitter and receiver pair to detect rotational speed or object movement.

Working Principle: Detects interruptions in the infrared beam caused by rotating or moving objects, converting them into digital pulses.

Output: Digital signal output (high/low) suitable for direct interfacing with Arduino, ESP32, and other microcontrollers.

Sensitivity: Adjustable via onboard potentiometer for precise detection based on distance and speed.

Response Time: Fast response for accurate counting of rotations or movement events.

Build Quality: Compact and durable PCB design with a stable infrared sensor and indicator LED.

Applications: Ideal for measuring motor speed (RPM), wheel rotation, object counting, and automation or robotics projects.
