Question

Using Arduino create a program that performs the temperature control of an oven. The thermocouple sensor it works 0 oC at 100 oC delivering a voltage of 0V through a transducer to 5V. It is necessary to average the voltage of 10 sensor samples to have better accuracy in the measurement. If the average temperature is higher than 50 degrees then the cold water recirculation pump is turned on for 30 seconds. Simulate the sensor with a voltage divider using a potentiometer.

Answer 1

create a program that performs the temperature control of an oven. The thermocouple sensor it works 0 oC at 100 oC delivering a voltage of 0V through a transducer to 5V. It is necessary to average the voltage of 10 sensor samples to have better accuracy in the measurement. If the average temperature is higher than 50 degrees then the cold water recirculation pump is turned on for 30 seconds. Simulate the sensor with a voltage divider using a potentiometer.

Answer:

#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;
}
}
