IR Infrared Obstacle Avoidance Sensor 4-Pin

Description

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. Specification : Parameter Details Detection Distance 2cm – 40cm (adjustable via potentiometer) Detection Angle 35° Operating Voltage 3.3V – 5V DC Current Consumption ≥20mA Output Type Digital (TTL level, active low) Interface 4 pins (VCC, GND, OUT, EN) Dimensions Approximately 43mm x 16mm Weight Approximately 5g Operating Temperature -10°C to +50°C Frequency Centered at 38kHz (adjustable) Applications : Robotics: Implementing obstacle avoidance and line-following capabilities in autonomous robots and smart cars. Automation Systems: Detecting and counting objects in automated processes, such as on conveyor belts or in product sorting systems. Security Systems: Monitoring for intrusions or unauthorized objects in restricted areas. Industrial Applications: Monitoring liquid levels, detecting items on production lines, or preventing equipment collisions. Smart Devices: Enabling anti-drop mechanisms or proximity detection in consumer electronics and IoT devices. Package includes : 1 x IR Infrared Obstacle Avoidance Sensor 4-Pin
