==Objective==
This tutorial will display the temperature and humidity data data in Processing with a curve which measured by the AM2321 sensor.

==Equipment==
*'''[[Microduino-Core]]'''
*'''[[Microduino-FT232R]]'''
'''[[Microduino-Weatherstation]]'''
*Other equipment
**USB cable one

==Schematic==
We will use the Microduino-Weatherstation's AM2321 sensor directly.

==Program==

Refers to TemperatureHumidityData

TemperatureHumidityDataArduino

==Debug==

Step 1：Set up hardware system, as follows:

Step 2: Explain the code:

This example needs two parts code, one is Processing and the other is Microduino.

Microduino:

//Get the temperature and humidity data for Processing's display.

void loop()
{
am2321.read();
temperature=(float)am2321.temperature/10.0;
humidity=(float)am2321.humidity/10.0;
Serial.print(temperature);
Serial.print(",");
Serial.println(humidity);
delay(100);
}

Processing:

//Get the serial port data,
// is always my Arduino, so I open Serial.list()[0].
// Open whatever port is the one you're using.
myPort = new Serial(this, Serial.list()[0], 9600);
myPort.bufferUntil('\n'); // Trigger a SerialEvent on new line

//Use the different color's curve to display the data that Microduino sent and mark the table scale

void draw() {
background(255);
// Draw lines connecting all points
for (int i = 0; i < vals.length-1; i++) {
strokeWeight(1);
stroke(255,0,0);
line(i, vals[i], i+1, vals[i+1]);
stroke(0,0,255);
line(i, vals2[i], i+1, vals2[i+1]);
}
// Slide everything down in the array
for (int i = 0; i < vals.length-1; i++) {
vals[i] = vals[i+1];
vals2[i] = vals2[i+1];
}
String val = myPort.readStringUntil('\n');
if (val != null) {
val = trim(val);
println(val);
String tempAndHumidty[]=val.split(",");
temp=tempAndHumidty[0];
humidity=tempAndHumidty[1];
lux=Float.parseFloat(val);
}
vals[vals.length-1] = 200-temp;
vals2[vals.length-1] = 200-humidity;
//Display scale
fill(0, 0, 0);
text ( "200-", 370, 10);
text ( "--", 370, 50);
text ( "100-", 370, 100);
text ( "--", 370, 150);
text ( "0-", 370, 200);
//show current num
fill(255, 0, 0);
text ( "temp:"+temp+"'C", 0, 15);
fill(0, 0, 255);
text ( "humidity:"+humidity+"%", 0, 28);
}
Step 3: Compile the code and download it.

Step 4：After running, change the temperature around the sensor, obserbe the curve.

==Result==

Screen will display the temperature and humidity data curve, the temperature curve is red,and the humidity curve is bule. As follows:
