PCB Mounted Active Buzzer Module

PCB Mounted Active Buzzer Module

The Active Buzzer Module is a versatile digital transducer designed to produce alert sounds in a wide range of electronic applications. Powered by DC energy, it is commonly used in systems like computers, printers, copiers, alarms, digital toys, automotive electronics, phones, timers, and various other digital projects.

This PCB-mounted Active Buzzer Module is capable of generating sound tones within a frequency range of 1.5 to 2.5 kHz. By switching the buzzer on and off at different frequencies—achieved through PWM (Pulse Width Modulation) or delays—you can create a variety of tones to suit your project’s needs.

Ideal for adding auditory feedback or alerts to your project, this module is compatible with microcontrollers like Arduino and features a standard 2.54mm pin pitch for easy integration. When triggered by a square wave input signal on the I/O pin, the buzzer emits sound, making it a perfect choice for generating programmable alerts, alarms, or simply adding some noise to your designs.

This buzzer’s frequency can be varied to adjust the tone, allowing you to customize the sound output and make it as annoying or attention-grabbing as needed.
