Piezo Buzzer (Big) - Loud Audible Alert for Arduino, Alarm & Notification Projects

Add clear, attention-grabbing sound output to your electronic projects with this large Piezo Buzzer from The Engineer Store, Bengaluru. Featuring a bigger diaphragm for louder, more resonant tones, this buzzer is ideal for alarm systems, proximity alerts, timer notifications, and any application where audible feedback needs to cut through ambient noise. Its simple two-wire interface makes integration with Arduino, Raspberry Pi, and custom circuits effortless. Fast shipping across India with full technical support.

Specifications

Key Features

• Louder Output: Larger piezo diaphragm produces significantly higher sound pressure levels compared to small buzzers, ensuring alerts are heard in noisy environments.
• Wide Voltage Range: Operates from 3V to 12V DC, compatible with 3.3V and 5V microcontroller logic as well as 9V and 12V power supplies.
• Low Power Consumption: Draws minimal current (typically under 30 mA), making it safe to drive directly from most microcontroller GPIO pins with a transistor driver.
• Simple Integration: Two-wire connection-just power and ground (active type) or signal and ground (passive type)-no complex wiring or external amplifier needed.
• Versatile Tone Generation: Passive variant allows custom frequency and melody generation via PWM; active variant provides instant continuous tone on power-up.
• Compact Yet Powerful: Large enough for serious sound output while still fitting comfortably on breadboards, perfboards, and inside project enclosures.
• Durable Piezo Element: Solid-state construction with no moving mechanical parts-long lifespan with consistent performance over millions of cycles.

Project Ideas

• Intruder / Security Alarm: Pair with a PIR motion sensor and Arduino to trigger a loud audible alert when motion is detected in a secured area.
• Kitchen / Lab Timer: Build a countdown timer that emits a clear, hard-to-miss buzzer tone when time expires-no more missed alarms.
• Smoke & Gas Detector Alert: Use with MQ-series gas sensors to create an audible warning system for smoke, LPG, or CO detection.
• Obstacle Alert for Robots: Mount on a robot chassis and sound a warning tone when ultrasonic or IR sensors detect an obstacle within a threshold distance.
• Doorbell / Visitor Notification: Create a simple wireless or wired doorbell system with a push button, microcontroller, and this buzzer for the alert tone.
• Melody & Music Player: Use the passive variant with Arduino's tone() function to play custom melodies, jingles, or notification sounds.
• Industrial Machine Status Indicator: Integrate into control panels to provide audible feedback for error states, cycle completion, or operator attention required.
• Educational Electronics Kit: Ideal for teaching students about piezoelectric effect, PWM signal generation, frequency, and sound wave fundamentals.

How to Use

1. Identify Buzzer Type: Determine if your buzzer is active (has built-in oscillator-produces tone when DC voltage applied) or passive (requires external frequency signal).
