Aquí tienes una descripción detallada de cómo conectar los relevadores en el esquema:
Relevador para Electroválvula (Relevador 1):
  • Bobina del relevador:
    • Un terminal de la bobina se conecta a 5 V.
    • El otro terminal de la bobina se conecta al colector del transistor que la controla (por ejemplo, Q2).
  • Transistor de control:
    • La base del transistor se conecta, mediante un resistor de 1 kΩ, a la salida del canal comparador del LM358.
    • El emisor se conecta a Ground.
  • Protección (flyback):
    • Conecta un diodo 1N4007 en paralelo con la bobina: conecta el ánodo al nodo del transistor (colector) y el cátodo al 5 V. Esto previene picos de voltaje cuando se desenergiza la bobina.
Relevador para Buzzer (Relevador 2):
  • Bobina del relevador:
    • Un terminal de la bobina se conecta a 5 V.
    • El otro terminal se conecta al colector del transistor de control (por ejemplo, Q1).
  • Transistor de control:
    • La base de este transistor se conecta, mediante un resistor de 1 kΩ, a la salida del amplificador configurado como inversor (del segundo canal del LM358).
    • El emisor se conecta a Ground.
  • Protección (flyback):
    • Coloca otro diodo 1N4007 en paralelo con esta bobina, con la misma orientación: ánodo al colector del transistor y cátodo al 5 V.

Estas conexiones garantizan que al activarse la detección de flama:
  • Con salida alta en la etapa comparadora: - se energiza Q2, cerrando el camino para el relevador de la electroválvula.
  • Con salida baja en la etapa inversora: - se mantiene Q1 apagado, por lo que el buzzer permanece sin energizar.
En ausencia de flama, se invierte la lógica: el relevador de la electroválvula se desactiva y el relevador que activa el buzzer se energiza.
