Bonjour,
J’ai réalisé un capteur de distance pour détecter si une voiture est présente dans le garage (ou ailleurs).
Pour ceux que ça intéresse, je ne vais pas réalisé de tuto mais je partage rapidement ce que j’ai fais.
Matériel:
-ESP8266 (j’ai un type Wemos d1 Mini)
-Capteur Ă ultrasons HC-SR04
Application:
-Homeyduino
Il faudra ensuite par le logiciel Arduino IDE (dispo sur Mac et Windows) paramétrer et téléverser le code ci dessous dans la carte ESP8266 (sans oublier modifier votre type de carte et de télécharger les librairies adaptées, le sujet est traité partout sur le web).
Fixer l’adresse IP de votre ESP8266 dans votre routeur/box internet (C’est du moins conseillé)
Ajouter un device depuis l’application Homeyduino, elle devrait détecter votre carte avec le nom que vous lui aurez donné.
J’espère que ça en aidera certains.
Bonne année 2022!

Hello,
I made a distance sensor to detect if a car is present in the garage (or elsewhere).
For those who are interested, I will not do a tutorial but I quickly share what I have done.
Equipment:
-ESP8266 (I have a Wemos d1 Mini type)
-Hc-SR04 Ultrasonic Sensor
Application:
-Homeyduino
You will then have to use the Arduino IDE software (available on Mac and Windows) to configure and upload the code below in the ESP8266 card (without forgetting to change your card type and download the appropriate libraries, the subject is covered everywhere on the web) .
Set the IP address of your ESP8266 in your router / internet box (at least it is recommended)
Add a device from the Homeyduino application, it should detect your card with the name you have given it.
Hope this helps some.
Happy New Year 2022!
