Active Buzzer Module

Key Features:

1. Audible Output: Produces a continuous tone or sound when powered, making it suitable for generating alerts, alarms, or notification sounds.
2. Operating Voltage: Typically operates within a wide voltage range, commonly 3.3V to 5V DC, allowing flexibility in different electronic circuits and projects.
3. Built-in Oscillator Circuit: Includes an internal oscillator circuit that generates the frequency required for the buzzer to emit sound when powered.
4. Low Power Consumption: Consumes minimal power, making it suitable for battery-powered devices and applications where power efficiency is crucial.
5. Compact Size: Small form factor for easy integration into various electronic projects and circuits.
6. Ease of Integration: Requires minimal external components for operation, typically needing only a DC power supply connection to function.

Typical Specifications:

• Operating Voltage: 3.3V to 5V DC
• Sound Output: Generates a continuous audible tone when powered
• Current Consumption: Low current draw, typically around a few milliamperes (mA)
• Size: Compact module size, usually mounted on a small PCB with mounting holes for easy installation

Applications:

• Alert Systems: Used in alarm clocks, timers, and security systems to indicate events or alarms.
• Notification Devices: Integrated into electronic devices and gadgets to provide audible feedback or alerts.
