Microduino-Shake

Microduino-Shake is a vibration detection sensor. As a resistance strain vibration sensor, it uses the variation of resistance to express mechanical vibration of the object to be measured, which can be applied in all kinds of sensors, such as the resistance strain gauge.

Features

• Small size
• Adjustable detection sensibility

Specification

• Electrical specification
  • Digital signal input;
  • 3.3V~5V operation voltage;

• Tech parameters
  • Measurement range: 300 grams to thousands of kilograms;
  • Accuracy: 1/1000~1/10000.

• Size
  • Size of the sensor: 10mm*7mm;
  • Size of the board: 20mm*10mm;
  • 1.27mm-pitch 4Pin interface connects with Sensorhub.

• Connection method
  • Pin description: GND, VCC, signal output and NC(empty).

Note: The output signal is digital and it needs digital port to detect (D0~D13), which can connect to the pin (3-9) of Sensorhub with the corresponding pins (D4, D6, D8, D10 and D12).

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 Arduino IDE, select File→Examples→Basics→DigitalReadSerial program examples, choose the right board, compile and then download.

• int pushButton = 6; Define the input pin as D6. (Users can also custom the name.)
• pinMode(pushButton, INPUT); Define pushButton as the input pin.
• int buttonState = digitalRead(pushButton); Read values of the pushButton input pin.
• Open the serial monitor after download. You can tell if there is vibration or not by the detection value, which is "0" when there is no vibration or "1" under vibration. You can also adjust R3 resistance on the back of the sensor to change detection sensibility.

Hardware Buildup

• Connect Microduino-Shake with Sensorhub to the digital port D6, which refers to "Define pushButton" mentioned above and users can also change according to personal needs.
• For reference: Microduino-Sensorhub

• For reference: mCookie-Hub

• Connect the core, Sensorhub and Shake 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

• Open the serial monitor after download and you'll see vibration values.

Application

• It can be used as a vibration sensor.
