The Crash Sensor is a simple Single Pole Single Throw Switch (SPST). When the sensor is not press, the electrical path through it is "open" (electrons cannot flow through it). When the sensor is pressed, the electrical path through it is "closed" (electrons can flow through it). It is an input module which produces a HIGH or LOW voltage depending if pressed or not. A Core module can read the voltage value and determine the state of the Crash Sensor.

Usage

Basic Functionality

The Crash Sensor is a simple Single Pole Single Throw Switch (SPST). When the sensor is not press, the electrical path through it is "open" (electrons cannot flow through it). When the sensor is pressed, the electrical path through it is "closed" (electrons can flow through it). It is an input module which produces a HIGH or LOW voltage depending if pressed or not. A Core module can read the voltage value and determine the state of the Crash Sensor.

Programming

Introduction

The Crash Sensor is used as a simple input pin. Therefore, the pinMode and digitalRead functions will be used.

Key Functions

  • Required Libraries: None
  • Key Functions:
    • pinMode(pin_number, pin_mode) - sets the mode for the pin
      • pin_number - is the pin number that the sensor is connected to
      • pin_mode - is the mode to set the pin to. Either INPUT or OUTPUT
    • digitalRead(pin_number) - Reads the value of the pin
      • pin_number - is the pin number that the sensor is connected to

Example

This is a simple example which outputs the state of the Crash Sensor to the serial port terminal.

Note: Important lines of code are highlighted.

//Define the pin the sensor is connected to
const int CRASH_SENSOR_PIN = 6;

void setup(){
  // put your setup code here, to run once:

  //Initial serial communication port at 9600 baud
  Serial.begin(9600);

  //Configure the pin into input mode
  pinMode(CRASH_SENSOR_PIN, INPUT);
}

void loop(){
  // put your main code here, to run repeatedly:

  //Perform a digital read and store the value into pin_state variable
  int pin_state = digitalRead(CRASH_SENSOR_PIN);

  //Check if the sensor's state is HIGH (not pressed)
  if(pin_state == HIGH){
    Serial.println("Crash sensor is not pressed!");
  }
  //Check if the sensor's state is LOW (pressed)
  else if(pin_state == LOW){
    Serial.println("Crash sensor is pressed!");
  }
  else{}

  //delay 100ms between loops
  delay(100);
}

Copy and paste the code above to the Arduino IDE or

Download the above example:

  • Open the Serial Monitor (magnifier glass on top right) and set 9600 baud. This will display the serial output.

Program Download

Programming

  • Follow the Software Getting Started Guide.
  • Select the Board, Processor and Port.
  • Click [File]->[Open], browse to the project program address, and click "Microduino_LED_Test.ino" to open the program.
  • After confirming all these items are correct, click "→" to download the program to the development board.

Hardware Setup

  • Referring to the following picture, connect the Sensor-LED to the digital port D6 of Microduino-Sensorhub.
