Passive Buzzer 5V

The piezoelectric buzzer has a simple structure in which a ceramic piezoelectric disk is affixed to a vibrating plate. An alternative voltage applied to this element will cause a contraction or diametrical expansion of the element. This feature is used to fold a vibrating plate, which generates sounds. Passive Buzzer 5V features:

- Input voltage: 3V to 12V
- Diameter: 12mm
- Height: 7.5mm
- Pin spacing: 6.5mm
- Impedance: 16 Ohm
- Working frequency: 2 to 5 KHz
- Quantity: 1 unit

MAX9812L Amplified Microphone for Measuring Sound

The MAX9812 is a sound amplifier specially designed to treat the signal coming from microphones.
We can use it together with Arduino to measure sound from a processor like Arduino.
When we saw the modules with microphone we commented that, in general, the signal generated is too low to be registered correctly.
If we want to be able to measure sounds, we will have to amplify the signal. The MAX9812L has single / dual inputs, fixed gain of 20dB, bandwidth of 400 kHz, low noise and low signal distortion 0.015% THD.
There are two models, its supply voltage is 2.7V to 3.6V.
We can use the sensors with MAX9812 for applications that require measuring the intensity or frequency of the sound.
