Question

in Arduino program

A program that performs the temperature control of a furnace. The sensupermocupla operates from OC to 100C delivering through a transducer a voltage of 0V to 5V. It is necessary to average the voltage of 10 samples of the sensor to have a better accuracy in the measurement. If the average temperature is higher than 50C then the cold water recirculation pump is turned on for 30 seconds. Simulate the sensor with a voltage divider using a potentiometer.

Answer 1

#define sensor A1

float temperature = 0;
float Temperature = 0;
float voltage = 0;
int i=0;
void setup()
{
// put your setup code here, to run once:
pinMode(sensor, INPUT);
}

void loop()
{
// put your main code here, to run repeatedly:
//Sensor give values from (0-5)V for (0-100)C
temperature = analogRead(sensor) / 1024 * 5; //Converting ADC value to (0-5) V
//taking 10 Samples
voltage += temperature;
i++;
if (i == 10)
{
voltage = voltage / 10;
Temperature = voltage * 100 / 5;
Serial.print("Sensor value is ");
Serial.println(voltage);
Serial.print("Temperature value is ");
Serial.println(Temperature);
i = 0;
}
}
