⚙️ Components Used:
IR Sensor (for motion detection)
Relay Module (to control the buzzer)
Buzzer (alarm sound)
Lithium Battery (portable power)
Jumper Wires & Breadboard (for connections)
🔧 How It Works:
1️⃣ When a car (or object) enters the detection range of the IR sensor, it sends a signal.
2️⃣ The relay module activates, turning on the buzzer as an alert.
3️⃣ The system resets once the object moves away.
