Features:

A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.

Passive buzzer without oscillating source inside, so if you use DC signal, you can’t make it scream. It must be driven by a square wave of 2K~5K. The sound frequency is controllable, and the effect of ”do re mi fa so la si do” can be made. In some special cases, a control port can be multiplexed with the LED. Equipped with fixture nuts for convenient mounting. The module is driven by 9012 transistor.Uses 3 pin control port.

Specification:

EASY TO INSTALL : Designed with holes for fixing with bolt,so it is very convenient to install.
CONVENIENT PROGRAM CONTROL : Single chip microcomputer high and low level can make it sound, better than a passive buzzer. An active internal buzzer with shock source, so long as a power will be called 2 program easy to control, SCM can allow a high and low sounds, while passive buzzer cannot.
WORKING VOLTAGE : External connection of 3.3V-5V voltage, can be directly connected to 5V micro-controller and 3.3V micro-controller.
APPLICATIONS : Good for learning basic knowledge about various single board pc like UNO, PI, Tiny and sensor’s working , compatible with various other modules.
