Here is the [datasheet of the buzzer (PKMCS0909E4000-R1) ](https://www.mouser.com.tr/datasheet/2/281/PKMCS0909E4000-R1-1186610.pdf)on the module.
The Buzzer Module is an auditory feedback device. It is a perfect tool for educational purposes, alarm - security systems, musical systems and many other projects. Since it can emit sound with different frequencies, it can play different notes and create melodies.
The buzzer on the module is waiting for a input from the microcontroller. When a certain frequency provided, buzzer gets the required electrical signals and emit the sound with intended frequency.

**Here are some of the sample projects that include this module:**
Smart Doorlbell (including: SMD RED + RGB Module + Ultrasonic Distance Sensor Module + Buzzer Module)
The Python-based "Buzzer On/Off" application integrates an SMD Motor Driver, an add-on Buzzer Module, and an HC-SR04 Ultrasonic Sensor Module to form an interactive system that reacts to nearby objects. The project is crafted to demonstrate the practical application of combining hardware components with Python programming.
Seccurity System (including: SMD RED + RGB Module + Ultrasonic Distance Sensor Module + Buzzer Module)
The "Security System" application is a Python-based project that leverages hardware components to create a simple yet effective security monitoring system. This project utilizes an SMD Motor Driver, an RGB LED Module, a Buzzer Module, and an HC-SR04 Ultrasonic Distance Module. The system is designed to activate an alarm and visual warning signals if the detected distance falls below a predetermined threshold.
