Microduino-Sound

Microduino-Microphone is a sound detection sensor.

Feature

• Capacitance sound detection component;

Specification

• Electrical specification
  • Operation voltage: 3.3V~5V
  • Input device
• Tech parameters
  • Voltage measurement range: : 0～5V（Frequency range: 100Hz～4000Hz）；
  • Sound intensity range: 45～120dB；
  • Accuracy:±1%
• Size
  • Size of the sensor: 5mm*5mm，
  • Size of the board: 20mm*20mm
• 1.27mm-pitch 4Pin interface
• Connection method
  • Output: 0~5V analog signal
  • Pin description: GND, VCC, signal output and NC(empty). Since the output signal is simulated, it needs analog interface to detect (A0-A7), which can connect to Sensorhub with the corresponding pins (A6. A2 and A0).

Development

Preparation

• Make sure you build Microduino IDE or refer to: Microduino Getting started
• Core selection
  • 1. Adopt Microduino-CoreUSB or mCookie-CoreUSB as the core.
  • 2. Adopt Microduino-Core or Microduino-Core+ as the core plus Microduino-USBTTL as the program download module.

Program

• Open " AnalogInput " in the libraries.

• int sensorPin = A0; Define the analog A0 as the input pin.
• sensorValue = analogRead(sensorPin); Read values of the pin.

Hardware Buildup

• Stack all modules together and then connect the Sound sensor to the A0 slot of Microduino-Sensorhub with the wire.

For reference: Microduino-Sensorhub

For reference: mCookie-Hub

• Connect the core, Sensorhub and the Microduino- Microphone to a computer with a USB cable.
• Select the right board and COM port, compile and download. You can refer to AVR Core：Getting started

• Select the right port number from Tools→Serial Port in Arduino IDE after compiling, then download the program.
• Open the serial monitor after download. The values displayed on the serial monitor reflect the sound intensity currently detected by the Sound sensor.

Application

Microduino- Microphone is suitable for collecting sound or sound vibration detection.
