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 withArduino 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.
Buzzer module can be used for many kinds of controllers,especially Arduino UNO R3 comntroller is easier,it can be connected with Arduno sensor expansion boards by 3P line,and it can relize interact works with environmental perception.the module adopt zedoary technology,not only improve the performence of module,but also make the modulle with golden gloss.
