Sensor-Buzzer

The product number of Sensor-Buzzer is: MSDO11

Sensor-Buzzer is a passive buzzer. Like a magnetic speaker, it needs voltage with different frequency so that it can make sound accordingly. The pitch becomes louder when the frequency gets higher.

Introduction of Pins

  • Pins of the sensor:
    • PIN1: GND
    • PIN2: VCC
    • General signal pins:
      • PIN3(IO1): digital/analog signal
      • PIN4(IO2): NC(null)
    • Special signal pins:
      • If it is IIC: IO1/IO2 are respectively SDA/SCL.
      • If it is soft serial port: IO1/IO2 are respectively tx/rx.
  • Special to Sensor-Buzzer sensor pins
    • PIN1: GND
    • PIN2: VCC
    • PIN3(IO1): Output pin
    • PIN4(IO2): NC


Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.


Features

  • Controllable sound frequency (eg: You can achieve the effect of piano spectrum with it. )
  • Small size which is easy to install.

Specification

  • Voltage
    • 3.3V~5V working voltage
  • Size
    • Size of the board: 23.5mm*13mm
    • 1.27mm-spacing 4Pin interface connected with sensorhub.
    • The CAD drawing of the sensor: File:Sensor CAD.zip
  • Technical parameters
    • Drive with 2K~5K square wave
    • The sound frequency is controllable.
  • Connection
    • This sensor can be connected to the following interfaces of core: A0~A7,D2~D13
