IR Infrared Obstacle Avoidance Sensor Module
The IR Infrared Obstacle Avoidance Sensor Module is a compact, reliable, and versatile sensor designed for detecting obstacles in a wide range of electronic applications, including robotics, automation, and smart devices. This module operates by utilizing a pair of infrared components: a transmitter that emits infrared light and a receiver that detects the light reflected from nearby objects. When an obstacle is present within the detection range, the onboard comparator circuitry processes the signal, triggering a digital output (active low) and illuminating an indicator LED for visual feedback.
Features :
- Adjustable Detection Range: Configurable from 2cm to 40cm via an onboard potentiometer.
- Wide Operating Voltage: Supports 3.3V to 5V DC, ensuring compatibility with a variety of microcontrollers and systems.
- Digital Output: Provides a TTL-level signal (active low) when an obstacle is detected, simplifying interfacing with digital systems.
- Enable Pin (4-Pin Version): Allows external control to enable (EN = GND) or disable (EN = VCC) the sensor, with a default jumper to keep it enabled.
- Compact and Lightweight Design: Measures approximately 43mm x 16mm and weighs about 5g, ideal for space-constrained projects.
- Stable Performance: Reliable operation in ambient light or darkness, with good anti-jamming capabilities.
