Active Buzzer Module – 3.3-5V

Description

An Active Buzzer Alarm Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Just like what you are viewing now, it is 3.3V-5V DC Electronic Part Active Buzzer Module. Using top quality material, it is durable in use. An active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.

Features

Passive buzzer features

• Passive internal shocks without source- so if you can not make it with a DC signal tweet. Must be a square wave 2K ~ 5K to drive it.
• Sound frequency control- you can make a “more than a meter hair Suola” effect.
• In some special cases- you can reuse a control and LED mouth

Active buzzer features 

• An active buzzer with a concussion internal source- so long as it will be called an energized.
• Program easy to control- SCM can let a high-low sound- while passive buzzer did not.
