Story

Introduction

I built this project using XinaBox ☒CHIPS and Arduino IDE. It is a 5 min project , that allows you to read barometric pressure data received from the ☒SW01 on the serial monitor.This project is an adaption of my previous Easy Peasy Temperature Monitor project. Using the ☒CHIPS assembly is easy. The Arduino IDE software makes creating the code for the project simple.

Step 1: Downloading the Libraries

Go to Github.xinabox

Download xCore ZIP

Install it into Arduino IDE by going to "Sketch", "Include Library", then "Add .ZIP Library". As seen below.

Figure 1: Adding the ZIP libraries

Download xSW01 ZIP

Add the library the same way as you did for the xCore.

Step 2: Programming

Connect the IP01 and CC01 using an ☒BUS Connector. Make sure the ☒CHIPS' names are orientated correctly.

Figure 2: Connected IP01 and CC01

Insert into an available USB port.

Download or copy and paste the code from the "CODE" heading into your Arduino IDE. Alternatively you could create your own code using the relevant principles to achieve the same objective.

To ensure there are no errors compile the code.

After successful compilation(no errors found) you may upload the code to your ☒CHIPS. Ensure the switches are facing "A" and "DCE" respectively before uploading, if it is an IP01 with switches.

Step 3: Final assembly

Once the upload is successful, remove the IP01 from the USB port. Attach the SW01 with another ☒BUS Connector to the CC01.

Figure 3: Connected IP01, CC01 and SW01

Insert the board back into the same USB port.

Open the serial monitor in the top, right-hand corner of the screen. It should look like the image below after a few moments.

Figure 4: Serial Monitor displaying Pressure readings

You can now view altitude readings from the SW01 on the serial monitor.

PressureSM.ino

#include <xCore.h>  //add core library
#include <xSW01.h>  //add weather sensor library

xSW01 SW01;

const int DelayTime = 500; //Defining set delay time that could be used elsewhere in the code

//Create a variable to store the data read from SW01
float pressure;

void setup(){

  //Initialise variable to zero
  pressure = 0;
  
  //Start Serial Monitor
  Serial.begin(115200);

  //Start I2C communication
  Wire.begin();

  //Start SW01 Sensor
  SW01.begin();
  
  //String intro for project
  Serial.println("XinaBox Barometric Pressure Experiment");
  Serial.println("______________________________________");

  //Delay for sensor to normalise
  delay(3000);
  
}

void loop(){
  
  //Read and calculate data from SW01
  SW01.poll();

  //Request to get humidity, temperature and dew point data then store in the variables
  pressure = SW01.getPressure();


  //Display recorded data over the Serial Monitor

  Serial.print("Pressure:");
  Serial.print(pressure);
  Serial.println("Pa ");

  delay(5000);

}
