Piezo Buzzer

Overview:

The Piezo Buzzer is a compact and efficient sound-generating device used in alarms, notifications, timers, and electronic circuits. It is available in both active (self-driving) and passive (requires external frequency control) variants. This buzzer is widely used in Arduino projects, IoT applications, robotics, and industrial warning systems.

Key Features:

✔ Operating Voltage: 3V – 12V DC (Common: 5V)
✔ Compact & Lightweight: Small form factor for easy integration
✔ Loud & Clear Sound: Produces a strong beeping tone
✔ Two Variants Available:

• Active Buzzer: Generates a fixed sound when powered
• Passive Buzzer: Requires an external signal (PWM) for tone variation
  ✔ Low Power Consumption: Efficient energy usage
  ✔ Easy to Use: Simple 2-pin connection (VCC & GND)

Technical Details

How It Works:

1. Active Buzzer: Simply connect VCC and GND, and it will produce a sound.
2. Passive Buzzer: Requires a PWM signal from a microcontroller to generate different tones.

Applications:

🔔 Arduino & ESP32 Projects – Ideal for alerts, notifications, and sound effects.
⚠ Alarm & Security Systems – Used in intruder alarms, fire alarms, and warning indicators.
⏰ Timers & Reminders – Generates beeping sounds for countdowns and notifications.
🎵 Musical Applications – Can be programmed to generate tunes (Passive type only).
🤖 Robotics & Automation – Provides audio feedback in smart systems.

Package Includes:

✔ 1 x Piezo Buzzer (Active or Passive – Select Type)
