This tutorial is going to teach you some basics on using Active Buzzer Sensor Module.

Step 1: Introduction

Description:

An active buzzer sensor module has a built-in oscillation circuit, thus the sound frequency is fixed. It is able to generate the sound itself. So, you can simply turn it on and off with an Arduino pin, just like the way of turning on and off a Led which is connected to Arduino board. Besides, this sensor starts beeping when it is being supplied with DC power supply.

Specifications:

  • Operating voltage: 3.3V to 5V
  • Active low sensor module
  • Driver transistor: S8550
  • Size: 3.2cm x 1.3cm

Step 2: Pin Definition

Step 3: Sample Hardware Installation

Step 4: Sample Source Code

To get the result, please download the sample source code attached below and upload it into Arduino.

After uploading, listen to the sound that is produced by Buzzer. Have Fun!
