5v Active Alarm Buzzer 3 Pin Module for Arduino

A 5V active alarm buzzer is a small, electronic device that produces an audible sound when it is energized. Active Buzzer has three pins: a positive pin, a negative pin, and a control pin. The positive and negative pins provide power to the buzzer, and the control pin determines whether the buzzer sounds or not.

5V active alarm buzzers commonly use in Arduino projects, as they are easy to control with the Arduino’s digital output pins. They also use in a variety of other applications, such as alarm devices, timers, and confirmation of user input. Active low level trigger buzzers commonly use in electronic projects where it is necessary to produce a sound in response to a low voltage signal.

The input voltage of a 5V active alarm buzzer is typically between 3.3V and 5.5V DC. If you connect a 5V active buzzer to a voltage that is outside of its operating range, it may not work properly or it may be damaged.

The working principle of a 5V active alarm buzzer is based on the piezoelectric effect. When a voltage is applied to the buzzer, it causes a piezoelectric crystal to vibrate. This vibration creates sound waves, which are audible to the human ear.

The 3 pins of a 5V active alarm buzzer are:

• Positive pin: This pin is connected to the positive voltage of the power supply.
• Negative pin: This pin is connected to the negative voltage of the power supply.
• Control pin: This pin is connected to a digital output pin on the microcontroller.

When the control pin is low, the buzzer sounds. When the control pin is high, the buzzer is silent. The frequency of the sound produced by the buzzer can adjust by changing the voltage applied to the control pin.

Features : –

This active low level trigger buzzer is a type of buzzer that produces an audible sound when the voltage applied to its control pin is low. This means that the buzzer will sound when the control pin is connected to ground, and it will be silent when the control pin is connected to a high voltage. Here are some of the benefits of using a 5V active alarm buzzer:

• Easy to control
• Affordable
• Versatile
• Durable

5v Active Alarm Buzzer Specifications : –

The trigger level of an active low level trigger buzzer is the voltage level that must be applied to the control pin in order for the buzzer to sound. In this case, the trigger level is low, which means that the buzzer will sound when the control pin is connected to ground.

The resonance frequency of an active low level trigger buzzer is the frequency at which the buzzer will sound when it is operating at its optimal voltage. The resonance frequency of this type of buzzer is typically between 1kHz and 4kHz.

The sound level of an active low level trigger buzzer is the loudness of the sound that it produces. The sound level of this type of buzzer is typically around 80dB, which is considered to be a moderate level of loudness. here are some of the specifications of an active low level trigger buzzer:

• Operating voltage: 3.3V-5V
• Sound frequency: 1kHz-4kHz
• Sound level: 80dB
• Dimensions: 15mm x 8mm x 6mm
• Weight: 2g
• Trigger level: Active low
• Resonance frequency: 2500Hz±300Hz

5v Active Alarm Buzzer Applications : –

Active low level trigger buzzers use in a wide variety of applications, including:

• Alarms:
• Timers
• User feedback
• Music
• Security systems
• Industrial machines
• Medical devices
