Passive Buzzer

Overview

The Passive Buzzer is a fundamental component for adding sound to your electronics projects. Unlike an active buzzer, this passive variant requires an external signal to generate tones, giving you complete control over the frequency and allowing for the creation of melodies, alarms, and various sound effects. Its compact design and low power consumption make it perfect for Arduino, Raspberry Pi, and other microcontroller-based projects.

Key Features

• Wide Frequency Range: Produces tones from 1Hz to 5kHz, enabling a variety of sounds.
• Low Power Consumption: Operates at 5V, making it ideal for battery-powered projects.
• Simple 2-Pin Interface: Easy to connect to any microcontroller or driver circuit.
• Compact Size: Small footprint fits into tight spaces and DIY enclosures.
• Versatile Sound Generation: Create chirps, beeps, and even musical notes by varying the input frequency.

Technical Specifications

• Pins: 2 (positive and negative)
• Voltage: 5 V (DC)
• Frequency Range: 1 Hz - 5 kHz
• Operating Temperature: -20°C to +70°C
• Sound Pressure Level: ≥85 dB at 10 cm

Applications & Use Cases

• Arduino Projects: Add sound to your interactive projects, such as alarms, timers, and games.
• Embedded Systems: Provide audible feedback in industrial control systems, appliances, and IoT devices.
• Educational Kits: Teach students about frequency, waveforms, and sound generation.
• DIY Electronics: Create custom chimes, doorbells, or musical instruments.
• Prototyping: Quickly test audio output in your designs.

What's Included

• 1x Passive Buzzer (5V)

Compatibility

• Works with Arduino, Raspberry Pi, ESP32, STM32, and any microcontroller with a digital output pin.
• Can be driven directly from a GPIO pin or via a transistor for higher volume.
