Mapping of the Invisible Enviorment


For my project I want to collect the invisible elements (data) that shape the natural atmosphere on my walks and visualize them artistically.

On the route, light, air quality, temperature and pulse are measured every minute using an Arduino and sensors. These are stored via an SD card and read out with a code. The time and route are stored using a tracking app.The data determines the parameters of the subsequent image design. For transport, a "rack" is built that attaches the breadboard to the body. After each walk the collected Data will be read out and acryl painted onto a cardboardcanvas. For the background an abstracted version of the seen enviorment is painted.

  • Time/Duration= Size of the canvas
  • Route= Shape of the line
  • Temperature= Color
  • Light= Saturation of the color
  • Air quality= contour of the line
  • Pulse= Height of the line

 int gas = analogRead(A3);
 myFile.print( "Gas: ");
 myFile.println(gas, DEC);


 int pulse = analogRead(A2);
 myFile.print( "Pulse: ");

delay(60000); //collect data every minute // close the file:



  else {

// if the file didn't open, print an error:

 Serial.println("error opening test.txt");

} }



The place and the area of the walked route are indicated. Depending on what dominates the walk, a text (internal state) or a photo (external state) is attached. Also, an attempt is made to put this state in context with the collected data.
