Description:
These piezo buzzers utilize the piezoelectric effect, where a ceramic disc vibrates in response to an AC voltage to create sound waves. Because they lack an internal oscillator, they function similarly to a tiny speaker.
This 10-piece set is the standard for "beeper" feedback in consumer electronics, 3D printers, and DIY robotics. They are highly efficient, consuming very little power while providing a sharp, clear audible alert. Their PCB-mount design with standard pin spacing makes them compatible with breadboards and prototype shields.
Features:
Frequency Control: Capable of playing different musical notes and complex tones depending on the input signal frequency.
Low Power Consumption: Operates on very low current (<30mA), making them ideal for battery-powered IoT devices.
Compact Footprint: The 12mm diameter fits easily into tight enclosures or dense circuit board layouts.
Polarized Design: Clearly marked with a "+" on the top housing to ensure correct wiring to the anode.
Wide Voltage Range: Compatible with logic levels from 3V to 12V, fitting both 3.3V (ESP32) and 5V (Arduino) systems.
