The IR Infrared Obstacle Avoidance Sensor Module is a compact and reliable sensor designed to detect obstacles using infrared reflection. Ideal for robotics, automation, and DIY electronics projects, this module outputs a digital signal when an obstacle is detected. Featuring an LM393 comparator chip and adjustable detection range, it provides accurate and stable performance. With easy mounting options and compatibility with 3.3V to 5V systems, it is perfect for hobbyists, students, and engineers in Bangladesh.
Features:
-
Detection distance adjustable from 2cm to 80cm, ideal for close-range obstacle sensing
-
Detection angle: 35° for precise obstacle detection
-
LM393 comparator chip for accurate signal processing
-
Active Low output: gives low-level signal when an obstacle is detected
-
Onboard green LED indicator to visualize sensor activity
-
Three-wire interface: VCC, GND, and OUTPUT for easy connectivity
-
Works with 3.3V to 5V power supply
-
Onboard preset potentiometer to fine-tune detection distance
-
Compact design with 3mm mounting holes for easy installation
-
Suitable for robotics, line-following cars, automation projects, and DIY electronics
How to Use
-
Connect the VCC pin to a 3.3V – 5V power source
-
Connect the GND pin to the ground of the system
-
Connect the OUTPUT pin to a digital input pin on a microcontroller or development board
-
Adjust the onboard preset potentiometer to set the desired detection distance
-
Place the sensor in the path of the object to be detected; when an obstacle is detected, the OUTPUT pin goes LOW and the onboard LED lights up
-
Integrate into robotics, automated systems, or obstacle detection circuits for responsive operation
