Nesse tutorial, eu mostro como você pode criar um sensor de estacionamento com um ESP8266 e um sensor ultrassônico integrado ao Home Assistant.
- Produtos recomendados para uso com Home Assistant:
🔸 Wemos D1 Mini (ESP8266): https://s.click.aliexpress.com/e/_9vB7mA
🔸 Sensor Ultrassônico: https://s.click.aliexpress.com/e/_A9AYlg
🔸 Sensor Ultrassônico Resistente a água: https://s.click.aliexpress.com/e/_ACpGEi
🔸 Case de plástico (utilizei style 2-black): https://s.click.aliexpress.com/e/_AEDFTu
