Infrared IR Obstacle Avoidance Sensor Module

Description 
 The Infrared Obstacle Avoidance Sensor Module is a sensor that uses infrared light to detect objects in front of it. It is commonly used in robotics projects to enable robots to avoid obstacles. The sensitivity of the sensor can be adjusted using the onboard potentiometer. 
 Specifications 
 1. Operating Voltage: 3.3V - 5V 
 2. Output: 
 • Digital Output (DO): Binary signal (0 or 1 - High/Low) 
 • Analog Output (AO): Proportional to distance (not always available on all IR modules) 
 3. Detection Range: 2cm - 30cm (depending on adjustment and lighting conditions) 
 4. Adjustable Sensitivity: Via potentiometer (blue dial) 
 5. Current Consumption: ~20mA 
 6. Wavelength: Infrared Light (~940nm) 
 7. Pin Configuration: 
 • VCC: Power supply (3.3V or 5V) 
 • GND: Ground 
 • DO: Digital Output 
 • AO: Analog Output 
 8. Indicator LEDs: 
 • Power LED: Lights up when the module is powered. 
 • Signal LED: Lights up when an obstacle is detected. 
 9. Operating Temperature: -10°C to 50°C 
 10. Size: Compact, making it easy to integrate into various projects.
