High-Quality Passive Buzzer Module Low-Level Trigger Alarm for Arduino

The High-Quality Passive Buzzer Module is a reliable and efficient sound-generating solution for Arduino and microcontroller projects. Designed to operate with a working voltage of 3.3V to 5V, this module features a low-level trigger mechanism, making it suitable for alarm systems, control panels, and other sound-based applications. With its compact size and six fixed bolt holes for convenient installation, this module is easy to integrate into your projects. Unlike active buzzers, the passive buzzer requires an external 2k–5kHz square wave signal for operation, allowing users greater control over sound frequency. This versatility makes it ideal for custom sound effects and multi-tone alerts.
