Description
The Smart Car Obstacle Avoidance Sensor Module is an infrared-based detection module designed for autonomous vehicles and robotic platforms. It detects nearby obstacles and provides real-time digital feedback, enabling robots or smart cars to avoid collisions and adjust their path automatically.
With adjustable detection sensitivity and a compact design, this sensor is ideal for robotics projects, educational kits, and DIY smart vehicle applications.
Key Features
- Obstacle Detection: Detects objects in front of robots or vehicles
- Real-Time Digital Output: Instant feedback for path correction
- Adjustable Detection Range: Multi-turn potentiometer for sensitivity control
- Wide Voltage Support: Compatible with 3.3V and 5V systems
- TTL Output Signal: Easy integration with microcontrollers
- Compact & Lightweight Design: Ideal for small robotic platforms
- Durable Construction: Withstands vibrations and typical environmental conditions
Specification
- Working Voltage: DC 3.3V – 5V

- Weight: Approx. 9g
How It Works
- The module emits infrared light.
- When an object reflects the IR light back to the receiver, the sensor detects it.
- The output pin changes state (LOW when obstacle detected).
- A microcontroller (Arduino, ESP32, Raspberry Pi, etc.) reads the signal and adjusts movement accordingly.
Application
✔ Autonomous smart cars
✔ Line-following and obstacle-avoiding robots
✔ Robotics education kits
✔ DIY automation projects
✔ Collision detection systems.
