Active Buzzer Module – 3.3-5V – ROBOZONE

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.

Specifications of Active Buzzer Module:-

1.Product Name:3.3 to 5V Active Buzzer Alarm Module Sensor

2.Transistor drive module uses 8550

3. With fixed bolt hole- easy installation- 2.6mm aperture.

4. Operating voltage 3.3V-5V

5. PCB Dimensions: 34.28 mm (L) * 13.29 mm (W) * 11.5 mm (H)

Features:-

Passive buzzer features are:-

1. 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

2. Sound frequency control- you can make a “more than a meter hair Suola” effect.

3. In some special cases- you can reuse a control and LED mouth

Active buzzer features are:-

1. An active buzzer with a concussion internal source- so long as it will be called an energized

2. Program easy to control- SCM can let a high-low sound- while passive buzzer did not.

Module interface specification (3-wire) :-

+ External 3.3V-5V voltage (can be directly connected with the 5v and 3.3v MCU MCU)

– External GND out external microcontroller IO port
