Description
Passive Buzzer Module 5V - PWM input 2 kHz ~ 5 kHz, it is a very simple buzzer to use, it works by means of a square signal at an operating frequency between 2 kHz and 5 kHz.
The sound produced by this small device is controlled by the frequency values that the excitation signal is handling.
The module can use the 9012 transistor or the S8550 transistor, which allows the buzzer to work properly between 3.3V and 5V.
The Buzzer module can play melodies using the Arduino Tone function.
Specifications:
- DC operating voltage: 3.3V ~ 5V
- Approximate current of consumption: 30 mA
- Working frequency: 2 kHz ~ 5 kHz (square signal)
- Sound: 70 dB ~ 85 dB
- Passive type piezoelectric buzzer
