💡 What makes an active piezo buzzer easier to use than passive buzzers?

This handy alert device handles its own tone generation internally, which saves you from programming extra pulses.

- Direct plug in setup removes the need for external drivers or microcontroller timer interrupts

- Steady warning tones work perfectly for door chimes, equipment fault warnings, and safety interlocks
