Créer votre sonde d’humidité du sol autonome et solaire pour Home Assistant Vous en avez marre d’arroser votre pelouse ou vos plantes à l’aveugle ? Vous souhaitez optimiser votre consommation d’eau tout en gardant un jardin verdoyant ? Aujourd’hui, je vous présente un projet passionnant et très utile : la fabrication d’une sonde d’humidité du sol connectée, 100% autonome grâce à l’énergie solaire et parfaitement intégrée à Home Assistant. 💧☀️ Ce tutoriel vous guidera pas à pas, du choix des composants à la configuration logicielle, pour que vous puissiez vous aussi surveiller la santé de votre jardin intelligemment. Le projet : objectif autonomie et fiabilité L’idée de base est simple : mesurer le taux d’humidité de la terre et remonter l’information à Home Assistant. Mais le véritable défi est de rendre ce système complètement autonome en énergie pour pouvoir le placer n’importe où dans le jardin, sans se soucier des câbles ou de changer les piles. Pour y parvenir, notre stratégie repose sur trois piliers : Alimentation solaire : un petit panneau solaire couplé à une batterie rechargeable. Très basse consommation : utilisation du mode deep sleep (sommeil profond) de l’ESP32 pour ne consommer quasiment rien entre les mesures. Fiabilité des composants : choisir du matériel adapté à un usage en extérieur. Ce projet vous permettra d’obtenir des données précieuses pour déclencher un arrosage automatique, recevoir des notifications, ou simplement suivre l’état de votre sol au fil des saisons. Le matériel nécessaire Voici la liste des composants que j’ai utilisés. J’ai opté pour un bon rapport qualité/prix, avec du matériel facile à trouver. Le cerveau : une carte de développement ESP32. Son Wi-Fi intégré, sa faible consommation en sommeil profond et ses nombreux ports en font le candidat idéal. Le module d’alimentation : un module de charge solaire pour batterie 18650 (type TP4056 ou similaire). C’est la pièce maîtresse de notre système d’alimentation. Il gère la charge de la batterie via le panneau solaire et fournit une sortie stable pour alimenter l’ESP32. La batterie : une batterie lithium-ion de type 18650. Choisissez-en une avec une bonne capacité (ex: 2500-3400mAh) pour une meilleure autonomie, surtout en hiver. Le panneau solaire : un petit panneau solaire de 6V. Sa tension est parfaite pour le module de charge. La sonde d’humidité : une sonde d’humidité capacitive. C’est un choix crucial ! Contrairement aux sondes résistives (celles avec deux broches apparentes), les capacitives ne se corrodent pas au contact de la terre et de l’eau, assurant une bien meilleure fiabilité sur le long terme. La sonde de température/humidité (optionnel) : un capteur DHT11 ou DHT22 pour mesurer la température et l’humidité de l’air. C’est un petit plus pour avoir des données météo locales. Le boîtier : un boîtier de dérivation étanche (IP65 ou plus) pour protéger l’électronique des intempéries. Divers : des câbles de prototypage (fils Dupont), un fer à souder (optionnel mais recommandé), et un piquet (un tuteur en bambou fait parfaitement l’affaire) pour monter le panneau solaire. L’assemblage électronique Le montage est assez simple. Le cœur du système est le module de charge qui fait le lien entre le panneau solaire, la batterie et l’ESP32. Voici le schéma des connexions : Panneau solaire → module de charge : soudez les fils du panneau solaire aux bornes d’entrée « SOLAR +/- » du module. Batterie 18650 → module de charge : insérez la batterie dans son support sur le module, en respectant la polarité. Module de charge → ESP32 : connectez la sortie 5V du module à la broche VIN de l’ESP32, et la masse GND du module à une broche GND de l’ESP32. Sonde d’humidité capacitive → ESP32 : VCC → GPIO26 (on utilisera ce port pour n’alimenter la sonde que lors des mesures) GND → GND AOUT (Signal) → GPIO33 Sonde DHT11 → ESP32 : VCC → 3V3 GND → GND DATA → GPIO27 Mesure de la tension batterie → ESP32 : le module de charge inclut un pont diviseur de tension. Connectez la broche BAT du module (souvent au milieu) à la broche GPIO35 de l’ESP32 pour lire la tension. Une fois tout connecté, placez l’ensemble dans le boîtier étanche, en faisant sortir proprement les câbles du panneau solaire et de la sonde. La configuration avec ESPHome ESPHome est un outil fantastique qui transforme un code complexe en une configuration simple sous forme de fichier YAML. Voici le code complet, que nous allons décortiquer juste après. Note : n’oubliez pas de créer un fichier secrets.yaml dans votre dossier ESPHome pour y stocker vos informations sensibles (clé API, mots de passe Wi-Fi…). esphome: name: sonde-gazon friendly_name: Sonde Gazon on_boot: priority: -100 then: – output.turn_on: gpio_sensor – wait_until: condition: api.connected: – component.update: moisture – component.update: battery – component.update: battery_voltage – component.update: wifisignal – script.execute: deep_sleep_evaluation esp32: board: esp32dev framework: type: arduino # Activer les logs logger: # API pour Home Assistant api: encryption: key: !secret api_key # Remplacez par votre clé ota: password: !secret ota_password # Remplacez par votre mot de passe OTA wifi: ssid: !secret wifi_ssid password: !secret wifi_password manual_ip: static_ip: 192.168.0.177 gateway: 192.168.0.1 subnet: 255.255.255.0 fast_connect: true substitutions: sleep_duration: 1h moisture_min: "2.60500" # À calibrer à sec moisture_max: "1.50000" # À calibrer dans l'eau deep_sleep: id: deep_sleep_enabled sleep_duration: ${sleep_duration} binary_sensor: – platform: homeassistant id: prevent_deep_sleep entity_id: input_boolean.deep_sleep # Un interrupteur virtuel dans HA pour la maintenance publish_initial_state: true output: – platform: gpio pin: GPIO26 id: gpio_sensor sensor: – platform: wifi_signal name: "WiFi Signal" id: "wifisignal" – platform: adc pin: 33 name: "Moisture" id: "moisture" icon: "mdi:watering-can" device_class: 'moisture' state_class: 'measurement' attenuation: 12db accuracy_decimals: 1 unit_of_measurement: '%' filters: – calibrate_linear: – ${moisture_min} -> 0.0 – ${moisture_max} -> 100.0 – platform: adc pin: number: 35 allow_other_uses: true name: "Battery" id: "battery" device_class: 'battery' attenuation: 12db unit_of_measurement: '%' filters: – multiply: 2 # Le pont diviseur divise la tension par 2 – calibrate_linear: – 3.0 -> 0 – 4.2 -> 100 – platform: adc pin: number: 35 name: "Battery Voltage" id: "battery_voltage" attenuation: 12db unit_of_measurement: "V" icon: "mdi:battery-high" device_class: "voltage" state_class: "measurement" accuracy_decimals: 2

Support mural pour vinyles
Support mural pour vinyles Affichez votre passion musicale avec style : Mon projet de support mural pour Vinyles en impression 3D La musique a toujours été une part importante de ma vie et ma collection de vinyles est une véritable manifestation de cette passion. Cependant, pendant longtemps, mes précieux disques étaient inexploités, invisibles pour moi même et mes invités. C’est alors que j’ai eu l’idée de créer un support mural unique pour mes vinyles en utilisant l’impression 3D. Dans cet article, je vais partager avec vous les détails de mon projet, comment je l’ai conçu à l’aide d’un logiciel de modélisation 3D, et comment il peut transformer votre espace en une galerie d’art musicale personnelle. Le concept et la modélisation L’idée derrière ce projet était de mettre en valeur ma collection de vinyles d’une manière artistique tout en les gardant facilement accessibles. Pour ce faire, j’ai entrepris une série d’essais et d’itérations en utilisant un logiciel de modélisation 3D. Cette phase de conception était cruciale pour répondre aux contraintes spécifiques liées au poids des vinyles, à la méthode de fixation au mur, ainsi qu’à la solidité du support. Au fil de ces essais, j’ai pu affiner mon design pour garantir qu’il serait à la fois esthétiquement élégant et fonctionnel. J’ai opté pour une forme simple, conçue pour insérer élégamment le vinyle tout en maintenant une apparence épurée, mais cela a nécessité plusieurs itérations pour obtenir la solution idéale. J’ai également dû prendre en compte la solidité du support pour garantir qu’il puisse supporter le poids des vinyles sans risquer de se casser, de s’affaisser ou tout simplement tomber. L’impression 3D Après avoir finalisé le design de mon support, je suis passé à l’étape de l’impression 3D. Cette technologie révolutionnaire m’a permis de donner vie à mon concept. J’ai utilisé ma FLSUN v400 pour créer mes supports en utilisant du PLA, un matériau durable et respectueux de l’environnement. L’impression 3D s’est avérée être la méthode parfaite pour créer ces supports, car elle offrait une grande flexibilité en termes de design et de personnalisation. De plus, elle permet de produire des pièces avec une grande précision, assurant ainsi un ajustement parfait pour chaque vinyle. Un installation facile Une des caractéristiques les plus pratiques de ce support est sa facilité d’installation. Vous pouvez choisir de le fixer au mur à l’aide de scotch double-face pour éviter tout dommage permanent à vos murs, ou bien l’accrocher avec un petit clou discret. Cette polyvalence rend le support idéal pour différents murs. De plus, il est conçu pour maintenir fermement le vinyle en place tout en permettant un retrait sans effort lorsque vous souhaitez changer votre sélection musicale. Conclusion Ce projet de support mural pour vinyles en impression 3D, a ajouté une dimension artistique et fonctionnelle à mon espace de vie. Non seulement il met en valeur ma collection de vinyles d’une manière unique, mais il offre également une solution pratique pour les exposer et les écouter facilement.
