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 Document Schematic diagram: File:Sensor-Buzzer.Zip Development Program Download Download and unzip the program File:Sensor-Buzzer Test.zip Programming Follow the Software Getting Started Guide.
