Buzzer Module Sensor for Arduino


Product Description




Buzzer use dc power supply, as voice device widely used in electronic products like computer, printer, duplicator, alarm, electronic toy, auto electronic equipment, telephone and timer.

Active buzzer directly connected to 5V rated supply, this can be continuous sounding. The module combining with Arduino sensor shield can do simple circuit design "plug and play."

This versatile piezo-element module can be used for both input and output! It can be used as a noise-maker driven by your microcontroller for audible feedback of events,besides it can also be used as a knock-detector input to sense events and react to them.
