Mini station m t o qualit de l air 63086aaf-fc4d-4934-98a0-e9de7fd02b9f.jpg
Création d'une station météo capable d'analyser la qualité de l'air. Prototype réalisé dans le cadre du Hackathon Kit4kids 2019 par Denis Bernabeu, Lucas Dupor et Sylvain Charron

Introduction

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.
  • Fichiers

Étape 1 - Placer la carte sur la Breadboard

Après avoir soudé la carte à une embase à broches, la placer sur la Breadboard.


Étape 2 - Connecter les capteurs à la carte

Une fois la carte placée sur la Breadboard, les 2 capteurs se connectent de la façon suivante (voir schéma).

Étape 3 - Téléverser le code de la station météo

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


Étape 4 - Préparer l'alimentation de la station météo

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


Étape 5 - Construire le boîtier de la station météo

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.



Étape 6 - Placer les éléments dans le support

Comment ça marche ?

Observations : que voit-on ?

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


Applications : dans la vie de tous les jours

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.

Éléments pédagogiques

Objectifs pédagogiques

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.
