Grove - Passive Buzzer

This is a 3-5V passive buzzer. You can change the PMW frequency to award different beep sounds to get a "buzzer music". Also, the buzzer can be set as an alarm for security applications. So get one and start your own project! Features Passive buzzer with wide compatibility: The sound frequency is controllable, and power consumption is small. Applicable to electronic watches, pocket calculators, electronic doorbells and electronic toys. Low power consumption: It is driven by voltage, so the current consumption is small, generally under 20mA, not more than 100mA. Easy to use: compatible with Grove port, just plug-and-play Piezo passive buzzers need to be connected to the audio output circuit to sound. The sound frequency is controllable, and power consumption is small, generally in 20ma below, not more than 100ma. In general, the piezoelectric buzzer is driven by a square wave (VP-P). The piezo passive buzzer has a small size, lightweight, thin thickness, power consumption, good reliability, and low cost. We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs. Click to explore the Grove Sensor family and get started to Grove your Idea.
