• 🚧 2 side-mounted IR obstacle detectors
• 🧱 2 mechanical bump switches for collision detection
• 🔧 Adjustable sensitivity via onboard potentiometers
• ⚙️ Digital outputs for all sensors (easy microcontroller interfacing)
• 🔌 Operating voltage: 3.3V to 5V
• 📐 Compact PCB with mounting holes

🛠️ Applications

• 🧠 Line-following robots (maze solvers, racers)
• 🚗 Obstacle-avoiding mobile platforms
• 🏫 STEM learning kits & Arduino-based projects
• 📦 Conveyor belt alignment or sorting robots
• 🧪 Smart motion robots in home or lab environments

⚠️ Notes

• ✅ Calibrate IR sensors with the onboard potentiometers
