Infrared Line/Object Presence Sensor – Adjustable Digital Output

Infrared Line/Object Presence Sensor – Adjustable Digital Output
This compact infrared sensor module is ideal for detecting objects or tracking lines in robotics, automation, and classroom projects. With adjustable sensitivity and a clean digital output, it provides reliable detection that can be directly interfaced with microcontrollers.

Key Features:

• Adjustable detection distance (approx. 2cm with white surfaces; distance varies with color and reflectivity).
• Operates from a wide 2.5V to 12V DC supply (recommended 5V for best performance and lifespan).
• Low power consumption: 18–20mA at 5V (can be modified for lower current, down to ~5mA if required).
• Digital output signal:
  • LOW when object detected
  • HIGH when no object detected
• TTL compatible output (works directly with 3.3V or 5V MCU I/O ports).

Perfect for building line-following robots, object detection systems, and interactive electronic experiments.
