IR Infrared Obstacle Detector Sensor Module (Adjustable)

Overview: The Simple Solution for Robotics Navigation

The IR Infrared Obstacle Detector Sensor Module is the ideal, low-cost component for adding object detection capabilities to any microcontroller-based project. This module operates by using a pair of infrared components: an IR LED Emitter and an IR Photodiode Receiver.

When the emitted infrared light reflects off a nearby object, the photodiode detects the returned light. The onboard circuit, usually based on an LM393 comparator, then converts this signal into a clean, simple Digital Output (HIGH or LOW).

For students and engineers in Bangladesh building mobile robots, automatic gates, or digital counting systems, this module is a core building block. It features an onboard potentiometer that allows you to easily adjust the sensor's sensitivity and detection range (typically 2cm to 30cm), ensuring trusted and stable performance in various environments.

Key Technical Features: Simplicity and Adjustment

• Sensing Method: Infrared Reflection (Active IR Emitter/Receiver Pair).

• Detector Chip: Uses the stable LM393 Comparator IC for a clean digital output signal.

• Output Type: Digital Output (D0) (LOW when an object is detected, HIGH when clear—or vice versa, depending on setup).

• Detection Range: Adjustable via potentiometer, typically from 2cm up to 30cm.

• Operating Voltage: Wide compatibility with 3.3V to 5V DC supply.

• Adjustment: Onboard potentiometer for fine-tuning the sensing distance threshold.

• Indicators: Includes a Power LED and an Output Status LED for easy testing and debugging.

• Functionality: Provides non-contact, quick-response object detection.

Applications: Dependable Results for Automation

• Obstacle Avoidance Robotics: Detecting walls, furniture, or other robots in the path of a mobile vehicle.

• Digital Counters: Counting items as they pass the sensor on a conveyor or through an opening.

• Line Follower Robots: Can be used with color detection to identify lines or edges.

• Automatic Doors/Gates: Implementing simple proximity detection for activation.
