Buzzers & Audio Modules

Buzzers and audio modules are actuators used to generate tones and acoustic signals in IoT, smart home, and embedded projects.

They can easily be controlled using microcontrollers such as ESP32, ESP8266, or Arduino-compatible boards, providing quick audio feedback in electronic systems.

Common variants include active and passive buzzers as well as audio modules with advanced sound and tone generation capabilities.

Typical applications include alarm systems, status indicators, notifications, warning systems, and acoustic feedback in user interfaces.

When selecting a module, pay particular attention to operating voltage, sound level, frequency range, and the module type (active or passive).

Tip: Use the filters to quickly find the right buzzer or audio module based on type, voltage, or application.
