Real-Time-Temperature-Plot-VSCSharp-Arduino

Example Real-time temperature graph between C#.NET and Arduino

Using ZedGraph Library (http://zedgraph.sourceforge.net/samples.html)

• Arduino UNO R3 Code:*

  #include <math.h>
  
  #define RESISTOR_CONNECT_THERMISTOR	10000
  
  void setup() {
    Serial.begin(9600);
  }
  
  void loop() {
    Serial.println((Temperature(analogRead(0))));  // display Celsius
    delay(1000);
  }
  
  /* Calculate the temperature according to the following formula. (Steinhart-Hart Equation)
     https://learn.adafruit.com/thermistor/using-a-thermistor
  */
  
  float Temperature(int RawADC) {
    float temperature,resistance;
    // Calculate the resistance of thethermistor
    resistance   = (float)(1023-RawADC)*RESISTOR_CONNECT_THERMISTOR/RawADC;
    int B = 3975;
    temperature  = 1/(log(resistance/RESISTOR_CONNECT_THERMISTOR)/B+1/298.15)-273.15;
    return temperature;
  }
