Hello, I can help with your "Sistema Ecológico de Reaproveitamento de Água" project. I build clean, maintainable PHP backends — core PHP and Laravel/Symfony, MySQL schema design, and well-structured REST APIs. For work involving php, javascript, microcontroller, electrical engineering, html5, html, arduino, circuit design, embedded systems, automation, I pay close attention to validation, security, and readable code, delivering in small, testable milestones. I provide clean commits and clear documentation. Can we discuss the specifics before I firm up the timeline? ⭐ 5.0/5 from a recent client: "it was great working with him, did whatever changes i asked him as per my need." Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

Olá, sou engenheiro de sistemas embarcados com mais de 16 anos de experiência em ESP32, sensores, automação, controle de bombas/válvulas, LCD I2C e interfaces web para protótipos funcionais. Posso desenvolver o sistema de reaproveitamento de água para a horta doméstica com código-fonte organizado, leitura da umidade do solo e nível do reservatório, acionamento automático/manual da irrigação, display com status do sistema, painel web para monitoramento/acionamento remoto e alertas por SMS quando necessário. Também incluo diagrama de ligações e orientação para montagem e testes do protótipo. Minha abordagem será manter o projeto simples e confiável, adequado ao protótipo solicitado, mas já com uma estrutura de firmware clara para futuras melhorias caso vocês queiram expandir depois. Também posso orientar na escolha entre bomba d'água ou válvula solenoide e no módulo/serviço SMS mais adequado. Tenho algumas perguntas rápidas: vocês já possuem os componentes ou devo sugerir uma lista final? O SMS deve ser via serviço online como Twilio ou módulo GSM? Haverá Wi-Fi disponível no local? Posso incluir pequenos ajustes após a entrega para calibrar sensores e limites de irrigação. Entre em contato para discutirmos os detalhes.

Hi there, The challenge lies in ensuring reliable automation with the ESP32 to effectively monitor soil moisture and manage irrigation efficiently. Setting up the sensors and integrating them with the web interface can be complex if not planned properly. I propose a phased approach: first, focus on programming the ESP32 to read moisture and water level sensors, followed by developing the web interface for remote monitoring and control. This will ensure a functional prototype that meets your requirements for automation and user alerts. Do you have any specific preferences for the web interface features? Looking forward to discussing the details in chat.
