This project provides comprehensive functionality for an IoT device using ESP32. It supports Wi-Fi and MQTT for communication, has an asynchronous web server with webpage for configuration, handles OTA updates, reads sensor data, and controls relays and IR devices. The use of preferences and SPIFFS ensures that configuration data is stored persiste

Trabalho final de IOT do curso de Desenvolvimento de Sistemas do Senai na construção de uma comunicação MQTT utilizando uma placa ESP32, gerenciando informações de temperatura e humidade de um DHT22.

This project is an IoT-based pH monitoring system that measures the pH level and publishes the data to an MQTT broker. It also allows remote control of an LED through MQTT messages. The system uses an ESP32 microcontroller, connects to Wi-Fi, and interacts with the HiveMQ public MQTT broker.

Simple ESP project to switch a led remotely using MQTT, ESP8266, and a public broker.

An embedded system that assists users in managing medication schedules and storage, featuring synchronized alarms and environmental monitoring.
