3 Pieces 5V Buzzer Alarm Sounder for Arduino

Description

Technical Specifications

The BUZZER 5V module is an electronic component used to generate sounds, tones, or acoustic alarms in projects based on Arduino or other microcontrollers. It can be active or passive, with an integrated oscillator in the active case, making the use of the component simpler. In the passive case, a frequency signal must be provided to generate a sound, using functions like tone() in Arduino. This module is suitable for audible indications such as alerts, input confirmations, timers, and error notifications.

The BUZZER 5V module features two power pins (VCC and GND) and, in some cases, a third signal pin. The module size is compact, typically less than 2 cm. The power supply voltage is 5V DC and the typical current ranges from 10 to 30 mA. The operating frequency is approximately 2kHz for active buzzers.

To use the 5V buzzer module, it is necessary to connect it correctly to the microcontroller. The signal pin configuration depends on the type of buzzer (active or passive) and the project requirements.
