je me suis lancée dans l'utilisation de ThingSpeak pour envoyer les données d'un capteur de CO2, (+ humidité et température mais non utiles) et d'un capteur de turbidité.J'utilise une carte D1R32 avec shield grove (montage plus simple pour des élèves collège)
J'ai regardé pas mal de tutos pour finalement utiliser l'exemple fourni par ThingSpeak pour écrire sur un seul champ (capteur de CO2) et tout a très bien fonctionné.
J'ai donc ajouté le capteur de turbidité, sa valeur est bien envoyée dans la console j'obtiens une erreur pour l'nvoi dans ThingSpeak
Pouvez-vous me dire d'où vient l'erreur et comment la corriger SVP ?
Merci

Je n’utilise pas ThingSpeak mais à en croire le commentaire Que vous avez dans le code, si vous envoyez deux données ils faudrait peut être que la première soit dans le field 1 et la seconde dans le field 2 non ?
Je testerais donc avec
// Write to ThingSpeak. There are up to 8 fields in a channel, allowing you to store up to 8 different
// pieces of information in a channel. Here, we write to field 1.
int x = ThingSpeak.writeField(myChannelNumber, 1, result[0], myWriteAPIKey);
int y = ThingSpeak.writeField(myChannelNumber, 2, voltage, myWriteAPIKey);
(Attention quand vous postez du code à ne pas laisser des infos personnelles)
merci oui désolée j'ai copié le mauvais programme, j'avais corrigé cette erreur mais je n'arrive pas malgré tout à écrire la valeur de la turbidité dans ThingSpeak
Bonjour,
Pour écrire plusieurs données sur Thingspeak, il faut utiliser une autre méthode.
Essaye ce programme modifié qui écrit bien les deux valeurs sur Thingspeak.
Je n'ai pas les capteurs aussi j'ai remplacé result[0] et Voltage par des valeurs aléatoires.
