PinOut

The PinOut of the Iron is :

El Pinout del Soldador es: img

Legend:

PE : Protective earth goes directly to the metal part of the Iron

Heater : The Heater is around 12 Ohm +/- 1 Ohm

Thermocuple : This specific type of thermocuple generates a pretty low voltage (a few mV), since the arduino only reads 4.9mV per division (https://www.arduino.cc/reference/en/language/functions/analog-io/analogread/) we need an amplifier for the Arduino to read the small voltage .

Leyenda:

PE : Tierra va directamente a la parte metálica del soldador

Calentador : solo el calentador su alrededor de 12 Ohm +/- 1 Ohm

Termocupla : Este tipo de termocupla especifico genera una pequeña tension (unos pocos mV) al momento de calentar necesitamos utilizar un pequeño amplificador para que el arduino lo pueda leer (El arduino tiene una resolución de 4.9 mV por división para más información: https://www.arduino.cc/reference/en/language/functions/analog-io/analogread/ ).

Amplifier / Amplificador

Section under work/ sección en proceso

As mentioned on the PinOut section we need to amplify the output of the thermocuple ,after some investigatión i've decided to use an non-inverting OPAMP (Operational amplifier).

What is an Operational Amplifier? It's a type of amplifier that is more stable than a transistor for some impedance stuff. The formula to calculate the gain of the opamp is: img

img1

R1 = Ri R2 = Rf

To calculate the gain needed we just divide the needed voltage by our voltage

Como mencioné en la sección de pinout necesitamos amplificar la salida de la termocupla, despues de un poco de investigación llegué a la conclusión de que hay que usar un OPAMP (amplificador Operacional no invirtiente?).

Que es un amplificador operacional? Es un tipo des amplificador que tiende a ser maás estable que un transistor deido a algunos temas de impadancia.

La formula para el calculo de ganancia es: img

img1

R1 = Ri R2 = Rf

Para calcular la ganancia de solo debemos dividir la tension objetivo sobre nuestra tensión
