🧠 Perfect For
🚗 Obstacle-avoiding robots
📦 Object detection & sorting systems
🛠️ Industrial automation
🖥️ Touchless control panels
🎓 STEM and electronic learning kits

🛠️ How It Works
1️⃣ Sensor emits infrared light
2️⃣ Measures the angle of reflection from nearby object
3️⃣ Outputs analog voltage (higher voltage = closer object)
📊 Use ADC (Analog to Digital Conversion) to convert the signal into distance data

🧠 Pro Tip: Pair it with an OLED display or buzzer to build interactive and smart distance-alert systems!
