IR Obstacle Sensor 4Pin Module

The IR Obstacle Sensor 4Pin Module is a compact infrared proximity detector designed for reliable obstacle sensing in electronic and robotic projects. Using infrared emission and reception, the module detects nearby objects with consistent performance across a range of lighting conditions while maintaining low power consumption and fast response time.

Engineered for straightforward integration, the module features a simple 4-pin configuration that ensures easy connection and broad compatibility with most microcontrollers and control boards. Its compact footprint allows placement in tight spaces and on small assemblies where space and weight are constrained.

• 4-pin configuration for easy wiring and quick prototyping
• Infrared detection range up to several centimeters for short-range obstacle sensing
• Compact module size suitable for confined mounting locations
• Low power consumption appropriate for battery-powered applications
• Fast response time for real-time detection in dynamic systems

This module compares favorably with typical obstacle sensors by combining a simplified pin layout with improvements in power efficiency and response speed relative to earlier designs. It is well suited to applications such as mobile robots, line-followers with obstacle avoidance, automated prototypes, and other embedded projects that require dependable short-range detection and straightforward wiring.
