Le but de ce tutoriel est d'assembler une station météo équipée pour afficher la température, l'humidité et la concentration en gaz nocifs.
Cette station se veut simple d'utilisation et réalisable à bas coût.Après avoir soudé la carte à une embase à broches, la placer sur la Breadboard.
Une fois la carte placée sur la Breadboard, les 2 capteurs se connectent de la façon suivante (voir schéma).
Connecter la carte à l'ordinateur en utilisant un câble USB / micro USB.
Une fois cela fait, ouvrir le logiciel Arduino et télécharger la bibliothèque correspondant au capteur DHT 22 et compatible avec la carte Heltech : DHTesp.
Une fois cela fait, utiliser le code ci-dessus qui permet de récupérer les données envoyées par les capteurs et de les afficher sur l'écran de la carte :
Pour une utilisation plus complète de la carte Heltech, se reporter au schéma suivant qui explique plus en détails le rôle des différents PINS :
https://user-images.githubusercontent.com/3751318/37211768-50f5be2c-23ad-11e8-9385-416477cd0312.png
La station fonctionne au moyen d'une batterie 18650 que l'on installe sur un support.
Connecter la sortie 5 Volts de ce support à la borne 5V de la carte Heltech sur la Breadboard.
Remarque : on peut également utiliser d'autres batteries
Le plus simple est d'opter pour une boîte en carton parallélépipédique.
Avec le matériel décrit sur cette page, les dimensions étaient celles décrites sur la photo du patron.
La station affiche la température et l'humidité ambiante, et prévient si le taux en gaz nocif dépasse un certain seuil, affichant alors un message de danger
Le dispositif peut servir, dans une pièce à vivre, à s'informer de la qualité de l'air.
Il serait aussi envisageable de communiquer des relevés de données à distance grâce à la liaison wi-fi de la carte.
Plusieurs niveaux possibles d'utilisation pédagogique :
- partir de zéro et assembler la station météo
- observer une station déjà assemblée et en détailler les différents composants, leur rôle, les connexions les reliant les uns aux autres, etc.
- récolter les données transmises par une station pour les exploiter, pourquoi pas en faisant varier les lieux , et en tirer des conclusions.
