## About the project

The real-time online platform integrating ESP32、Express routing and MongoDB allows you to easily monitor the temperature and humidity of the surrounding environment.

## System implementation episode 1：ESP32

ESP32 is mainly responsible for：

- Connect to WiFi.

- Make a https post request：

  - Send the https request headers and request body

  - Set up railway server certificate

- Capture temperature and humidity information through DHT11 sensor.

- Process and send the temperature and humidity data in JSON format to MongoDB.

## System implementation episode 2：Express

Express is mainly responsible for：

- Create web application routes.

- Create EJS webpage.

- Executing middlewares.

- Receive and process https post request.

## System implementation episode 3：mongoose & MongoDB

mongoose & MongoDB are mainly responsible for：

- Create database schema and model.

- Connect to MongoDB server.

- Collaborate with Express for CRUD operations.
