Product description

Features:
Internal oscillation source
The active piezoelectric buzzer module has low-level trigger and continuous sound output. It will alarm as long as it is powered on.
Convenient program control
The single-chip microcomputer can make it sound at high and low levels, which is better than a passive buzzer. An active internal buzzer with a vibration source can be easily controlled by calling 2 programs as long as it is powered on. The single-chip microcomputer can allow high and low sounds, but a passive buzzer cannot.
Operating Voltage
External 3.3V-5V voltage can be directly connected to 5V microcontroller and 3.3V microcontroller.
Driver
The module is driven by a 9012 transistor.
Easy to install
Designed with bolt fixing holes, it is very convenient to install.
