Buzzer Small – 5V Piezo Beeper

The Buzzer Small – 5V Piezo Beeper generates audible tones and alerts when driven by DC voltage or PWM signals. This small 5V active/passive buzzer is ideal for alarm systems, notification sounds, and audible feedback in projects.

Key Features

• 5V operation
• Piezoelectric element
• Compact size
• Low current consumption
• Audible frequency range
• Easy interfacing with microcontroller
• Through-hole mounting

Technical Specifications

Applications

• Alarm systems
• Notification alerts
• User feedback
• Game sound effects
• Timer alerts
• Electronic doorbells

Important Notes

• Verify active vs passive type – active has built-in oscillator
• Passive buzzer needs PWM for tone generation
• Active buzzer beeps with DC voltage only
• Use tone() function on Arduino for passive buzzers
• Current draw spikes at resonance frequency
