Active Buzzer Module

The Active Buzzer Module is a small board with an active buzzer and header pins, ready to connect to an Arduino, ESP32 or breadboard with jumper wires. The buzzer has a built-in oscillator, so it beeps at a fixed tone as soon as it is switched on, and you control it with a simple HIGH or LOW from any digital pin, with no tone signal needed.

Active Buzzer Module Specifications

• Type: active buzzer with internal oscillator
• Sound: single fixed tone
• Control: on/off from a digital output pin
• Connections: header pins for signal, power and ground (check the labels on the board)
• Form: module board, works with Dupont jumper wires

Active Buzzer Module Applications

• Alarm and warning sounds in security projects
• Timer, countdown and reminder beeps
• Button press and keypad feedback
• Sensor alerts, such as gas, flame or water level warnings
• Arduino and STEM classroom projects

What's in the Box

• 1 × active buzzer module

Tip: Some buzzer modules sound when the signal pin is HIGH and others when it is LOW, so test yours with digitalWrite() before writing your alarm logic. An active buzzer plays only one pitch; for melodies, use a passive buzzer with the tone() function.
