Active Buzzer 5v 5pcs #957

Description

An “Active Buzzer 5V” is a type of audio signaling device that is designed to generate sound when it receives a 5-volt DC power supply. It is an electronic component commonly used in various applications to produce audible alerts, notifications, or warning sounds. Here are the key features and characteristics of an active buzzer:

1. **Power Supply Voltage:** The “5V” in “Active Buzzer 5V” indicates that it operates on a 5-volt direct current (DC) power supply. It typically requires a stable and regulated 5V voltage source to function properly.

2. **Audible Alert:** Active buzzers generate sound when powered, and they are capable of producing a continuous tone or various sound frequencies, depending on their design and use.

3. **Built-in Oscillator:** Active buzzers have an internal oscillator circuit that generates the audio signal, allowing them to produce sound without external input. This distinguishes them from passive buzzers, which require an external oscillating signal.

4. **Continuous Sound:** Active buzzers can generate a continuous sound as long as they receive power. This makes them suitable for applications where a constant alert or sound is needed.

5. **Applications:** Active buzzers are commonly used in a wide range of applications, including alarms, timers, notifications, and warning systems. They can be found in electronic devices such as alarm clocks, home security systems, and DIY electronics projects.

6. **Polarity:** Active buzzers have polarity, meaning they have a positive (+) and a negative (-) lead. It’s important to connect them correctly to the power supply to generate sound. Reversing the polarity may not produce sound or could damage the buzzer.

7. **Sound Output Level:** The sound output level of an active buzzer can vary depending on the model and design. Some buzzers may produce relatively loud sounds, while others may be quieter.

8. **Mounting:** Active buzzers typically have mounting holes or tabs for easy installation on a PCB (printed circuit board) or in an enclosure.

9. **Tone and Frequency:** Some active buzzers are designed to produce a specific tone or frequency. Others can be programmed to generate different sounds.

When using an Active Buzzer 5V, it’s essential to provide the correct voltage and ensure that the polarity is observed during the connection to avoid any damage or malfunction. The specific sound characteristics of the buzzer, such as frequency and volume, should be considered for the intended application. Always refer to the manufacturer’s datasheet or instructions for proper usage and specifications.
