The Piezoelectric Buzzer is a small and efficient component to add to your system or project if you want to produce any sound feedback or sound an alarm. Its two-pin compact structure allows it to be easily used with a breadboard, perf-board, or even PCBs. This piezoelectric buzzer has 23mm diameter and 30mm spaced mount holes. It produces a 3.3kHz tone at an 85dB sound level when activated drawing a current less than 15mA. Supplied with a 100mm lead, it is designed for a 3 – 20V power supply but it is advisable to use a stable supply in this range. It is very popular among hobbyists and portable electronics due to its small size and easy to use.

Product Description

To use this buzzer, you can directly connect to any GPIO pin of your microcontroller board like Arduino, Raspberry Pi, or PIC and since it only draws 15mA maximum current, it wont damage your controller. Care should be taken to connect the positive terminal to the supply which is marked by a (+) sign over it.
