• INTERNAL OSCILLATING SOURCE : Active piezo electronic buzzer module with low level trigger and continous sound output.It will alarm as long as being energized.
• 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.
