Buzzer Piezo Transducer 2800Hz for Arduino, Raspberry Pi, PIC, STM, AVR - 3 to 24VDC

This is the 3 to 24v Piezo Transducer Buzzer at 2800Hz thisdevice is perfectly compatible in most common microcontroller includingraspberry pi, This buzzer requires no external oscillation simply a voltage ofbetween 3v to 12v dc, across the terminal and it will make a beep noise. These devicecomes with two wires attach and two screw mounting point so it can easily beintegrated onto a bread board or into a circuit.Specification Operating Voltage 3 to 24vRated Current: 40mA                                                                                                  Sound Output: 2800Hz at 30cm 90dBResonant Frequency: 2800 – 200HzOperating Temperature: 20 to 60 Degree CelsiusFixing Centre Diameter: 34mm Centre Diameter: 28mmHeight: 14.5mmHousing: PCABS Black
