Piezo Buzzer - PS1240

Piezo buzzers are used for making beeps, tones and alerts. This petite but loud buzzer can be driven with 3-30V peak-to-peak square wave. Connect one pin to ground and the other to a square wave output from a microcontroller or timer. For the loudest tones, use around 4 KHz but it works well from 2KHz to 10KHz. For extra loudness, use both pins connected to a microcontroller and swap which pin is high or low, doubling the volume.
