30mm Piezo Buzzer: 1-30V
his piezo sounder is an inexpensive way to add sound to your project.
The wide operating voltage of 1 – 30V and low current draw (5mA at 9V)
make it easy to control this buzzer directly from a microcontroller I/O line.
This piezo sounder is an inexpensive way to add sound to your project.
The wide operating voltage of 1 – 30V and low current draw
(5mA at 9V) make it easy to control this buzzer directly from a microcontroller I/O line.
The volume can be increased by driving the two pins differentially from two I/O lines.
These buzzers are manufactured for name-brand household applicances,
so you get the benefit of a well-engineered product at a mass-production price.
The pins on this buzzer can be jammed into a breadboard (it’s a little bit tight, but it fits).
Additional specifications can be found in the datasheet (1MB pdf).
