Using Thonny to record the data (Temp, Hum, Moist)
Using Visual Studio to run local server (ngrok.py)
Visual Studio receive data from R-pi (Thonny - wifi_local_dht11_moisture.py), and sending the json data to ngrok
ngrok redirect the data to back end (CSV, {'temperature': temperature, 'humidity': humidity, 'moisture': moisture})
Transmit sensor data to the server
User Story
As a Raspberry Pi device, I want to send sensor data to the server via HTTP so that the data can be stored and processed.
Description
This use case describes how the Raspberry Pi sends data collected from sensors to a central server. Sensor data from the Raspberry Pi must be transmitted to a central server for further processing and display
Acceptance Criteria
Testing
Normal Flow of Events
The Raspberry Pi packages the sensor data (temperature, humidity, and moisture) into an HTTP request. The Raspberry Pi sends the data to the server endpoint via an HTTP POST request. The server receives the data, validates it, and stores it in a database. The server responds with a success message (HTTP 200 OK).
Alternate/Exceptional Flows:
S-1: Network connection failure
he Raspberry Pi fails to send data due to network issues. The Raspberry Pi retries sending data after a specified interval (e.g., 30 seconds).
S-2: Invalid data format
The server rejects the data due to invalid formatting (e.g., missing fields). The Raspberry Pi logs the error and resends properly formatted data.
