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

Parameter Specification
Type Piezoelectric buzzer
Operating Voltage 3V – 5V
Current Draw < 30mA
Sound Output ~85dB at 10cm
Frequency 2kHz typical
Package Through-hole
Dimensions 12mm x 8mm

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
