bonjour, je souhaite automatiser un changement d eau,sans passer par des capteurs de niveaux qui sont souvent sources de problemes.
l idée est d utiliser 2 capteurs de débit avec effet hall de type Capteur de débit YFS201 - Débitmètres | GO TRONIC .
j ai besoin de quelque chose de simple, la carte arduino sera activée à l heure demandée par un automate industrielle (celui ci ne gerant pas le pwm j ai besoin de l arduino), donc je n ai pas besoin d 'horloge. je n ai pas besoin non plus d affichage a l'ecran. j ai essayé de prendre des bouts de codes et de faire quelque chose mais des erreurs ou mauvais choix trainent,si quelqu un pouvait me corriger..merci
sequence des actions:
1)automate met sous tension l arduino
2)l 'arduino derive l 'eau ,en fermant une electrovanne du circuit et ouvrant l 'electrovanne pour evacuer l 'eau .
le temps d evacuation de l eau sera une constante (delay 120000 ). je voudrai recuperer la quantité d eau qui s'est evacuée pendant ce temps.
3) ouverture electrovanne eau propre,fermeture d une autre
4) ajout d eau nouvelle pour egaler celle evacuée grace au 2eme capteurs.
5)fin de l operation et pas de boucle continue
