Bonjour,
Je suis actuellement en cour de projet en entreprise.
Grâce a une carte Raspberry, mon but est de chronométrer le temps d’étuve d’un four.
Voici mon problème :
Le chronomètre se déclenche lorsque la température dépasse le seuil de 25°C puis se s’arrête lorsque la température est inférieur à 25°C et reprend son cycle lorsque que la température repasse la consigne de 25°C.
Cependant, le chrono prend en compte le temps passé en dessous du seuil de 25°C ce que ne souhaite pas, auriez vous une astuce afin de régler ce problème ?
Je vous fourni ci-dessous le programme actuel, en vous remerciant pour votre aide et pour vos réponse.
