Active Buzzer Alarm Module
This is a small buzzer module which operates around the audible 2 kHz frequency range. It is an active buzzer, which means that it produces sound by itself, without needing an external frequency generator.
It can easily be used with microcontroller boards, like Arduino, without needing a dedicated PWM channel.
