Arduino-NTC-Libary

This libary calculates NTC's resistance and temperature. http://www.giangrandi.ch/electronics/ntc/ntc.shtml Formulations basis from this paper.

Connection Schematic:

Using:

• Import Libary

      #include "ArduinoNTCLibary.h"
      // Firstly must check dependencies at the end of the page.

• Construct Object

      NTC termistor_1 = NTC();`

• Configure NTC's params

      termistor_1.setNTCPin(A0); // Input sensor pin.
      termistor_1.setReferanceResistance(10000); // Referance resistance value
      termistor_1.setReferanceBetaConfidency(3900.0); // Can calculate with paper.
      termistor_1.setReferanceResistanceAt25C(2250.0); // Can find datasheet of NTC.
      termistor_1.setReferanceMaxVoltageOfADC(4.60); // ADC's supply voltage. Measure 5V pin.  
      termistor_1.setReferanceMaxADC(1024.00); // ADC reading bit value. 

• Measuring
  • Voltage Measuring :

     termistor_1.measureNTCVoltage(); // This method gets pin of input's voltage value.
     termistor_1.measureNTCVoltage(10); // Sampled instance method.  

  • Resistance Measuring :

     termistor_1.measureNTCResistance(); // This method gets NTC's Reistance value with calculating voltage.
     termistor_1.measureNTCResistance(10); // Sampled instance method.  

  • Temperature Measuring :

     termistor_1.measureNTCTemperatureCelcius();   // NTC's Temperature's value calculates with 
                                                  // voltage and resitance.
     termistor_1.measureNTCTemperatureCelcius(10); // Sampled instance method.  
     termistor_1.measureNTCTemperature(); // Fahreneit version

  • NTC's pin connection status :

     if(termistor_1.getNTCStatus()){
           // NTC Connected.
     }
     else{
           // NTC Not Connected.
     }

• Example Code

     // You can find this sketch in path /examples/basicCalculation/basicCalculation.ino
     #include "ArduinoNTCLibary.h"
     NTC termistor_1 = NTC();

     void setup(){
           Serial.begin(9600);
           termistor_1.setNTCPin(A0);
           termistor_1.setReferanceResistance(10000);
           termistor_1.setReferanceBetaConfidency(3900.0);
           termistor_1.setReferanceResistanceAt25C(2250.0);
           termistor_1.setReferanceMaxVoltageOfADC(4.60);
           termistor_1.setReferanceMaxADC(1024.00);
     }

     void loop(){
           int sample_count = 10;
           
           delay(1000);
           Serial.print("NTC Voltage >> ");
           Serial.print(termistor_1.measureNTCVoltage());
           Serial.print(" >> Sampled >>");
           Serial.println(termistor_1.measureNTCVoltage(sample_count));
           Serial.print("NTC Resistance >> ");
           Serial.print(termistor_1.measureNTCResistance());
           Serial.print(" >> Sampled >>");
           Serial.println(termistor_1.measureNTCResistance(sample_count));
           Serial.print("NTC Temperature >> ");
           Serial.print(termistor_1.measureNTCTemperatureCelcius());
           Serial.print(" >> Sampled >>");
           Serial.println(termistor_1.measureNTCTemperatureCelcius(sample_count));
           Serial.println("------------------------------------------------");
     }
