## Overview

This is an Arduino/ESP32 temperature-and-humidity monitor with serial controls, an HTTP API, and encrypted sensor-data uploads. The principal flow reads DHT measurements, builds a JSON payload, encrypts it, and posts it to a configured server when Wi-Fi is available. A separate API exposes health, sensor, configuration, and immediate-push endpoints. The tree identifies Main.ino as the firmware entry point, but its contents and the API/server setup wiring were not sampled, so no orchestration links are inferred. The README is empty.

Main entry points: [`HTRepo.cpp`](https://github.com/maruthisarathchandra/miniproject-/blob/main/HTRepo.cpp) (Upload repository), [`RestApiServer.cpp`](https://github.com/maruthisarathchandra/miniproject-/blob/main/RestApiServer.cpp) (REST API), [`WiFiConnect.cpp`](https://github.com/maruthisarathchandra/miniproject-/blob/main/WiFiConnect.cpp) (Wi-Fi manager), [`DHTReader.cpp`](https://github.com/maruthisarathchandra/miniproject-/blob/main/DHTReader.cpp) (Sensor reader)
