Arduino - Analog K-Type Thermocouple Amplifier-AD8495
The k-Type thermocouple sensor is analog-output amplifier
that is very simple to use with arduino. The power of board with 3-18VDC and
measure the output voltage on the out pin. To convert the voltage to
temperature use the following equation:
Temperature = (Voltage obtained – 1.25)/
0.005 V.
For example, if the voltage is 1.50VDC, the temperature is (1.50-1.25)/0,005=50°C.
If you connect 5V power the temperature range is -250°C to 750°C output (0 TO
5VDC) but is connect to 3.3V power the temperature range is -250°C
to 410°C (0 to 3.3VDC).
Materials:
- AD8495 sensor(from adafruit)
- Protoboard
- Arduino
- Three connecting wires
- K-Type Thermocouple
Wiring:
- Connect de K-Type thermocouple to AD8395 sensor.
- Place the sensor in the the protoboard.
- Connect the GND of the sensor with the GND of the arduino.
- Connect the V+ of sensor to 5v or 3.3v according the range of temperature that you want to read.
- Connect the Out to the A4 analogpin.
Code:
//Analog read pin
const int Out = A4;
void setup(){
Serial.begin(9600);
}
void loop(){
int A4 =
analogRead(4);
// equation to
calculated temperature
double Vin=(5*A4);
float vinl=Vin/1024;
double Vout=vinl-1.25;
double T = Vout/0.005;
Serial.print("Vin= ");
Serial.print(Vin);
Serial.print(" | vinl= ");
Serial.print(vinl);
Serial.print(" | Vout= ");
Serial.print(Vout);
//print temperature in Celsius
Serial.print(" | T= ");
Serial.print(T);
//print voltage read
Serial.print(" | A4= ");
Serial.println(A4);
delay (1000);
}

Termoeléctrico amplificador AD8495 tipo K
El sensor amplificador termoelélectrico tipo K con salida análoga es muy facil para utilizarse con arduino. Alimentar la tarjeta con 3-18VDC y medir el voltaje de salida. Para convertir el voltaje a temperatura use la siguiente ecuación: Temperatura = (Voltaje obtenido -1.25)/.0005V.
Por ejemplo si el voltaje es is 1.50 VDC, la temperatura es ( 1.50-1.25)/.0005= 50 grados Celsius.
Si alimentas con 5V el rango de temperatura esta entre -250 a 750 grados celsius de salida (0 a VDC) pero si es conectado a 3.3V el rango en la temperatura esta entre -250 a 410 grados celsius (0 a 3.3VDC).
Materiales:
1. Sensor AD8495 (de adafruit)
2. Tablero (protoboard)
3. Arduino
4. Tres cables de conexión
5. Termoeléctrico tipo K
Cableado:
1. Conecte el termoeléctrico tipo K al sensor.
2. Coloque el sensor en el tablero.
3. Conecte el GND del sensor con el GND del arduino.
4. Conecte el V+ del sensor a 5V ó 3.3V dependiendo del rango de temperatura que quieres leer.
5. Conecte la salida al puerto A4.
Código:
//Analog read pin
const int Out = A4;
void setup(){
Serial.begin(9600);
}
void loop(){
int A4 = analogRead(4);
// equation to calculated temperature
double Vin=(5*A4);
float vinl=Vin/1024;
double Vout=vinl-1.25;
double T = Vout/0.005;
