I used this website for the information and for the right library:(https://randomnerdtutorials.com/esp32-dht11-dht22-temperature-humidity-sensor-arduino-ide/).
Aside from the website i used my teammates for help where it was needed.
I wanted to make my own spin on the original design by including a button to activate the sensor and an LED to show if its on.
At first I tried to use my own DHT11, but apparently it didn't work. So i used one from my Teammates.
The rest of the tutorial was clear and worked like a charm.

### parsing JSON
The data that is send by the nodes is send in json data. We chose this becouse we can easily use the data within javascript, this is called parsing. We use the parced data and send that in to the next function to make the data more acceseble to use in further instences.
```js
const jsonData = JSON.parse(event.data);
// Use the parsed JSON data as needed
handleIncomingData(jsonData);
```
### Pro
Here is the function that receves the parced JSON data and set it into variables. So that it can be more easlily used in the next function with is the processNodeData, witch is setting the data in to the right array.

function handleIncomingData(data) {

In the function processNodeData we first check if there is a array for the node that is sending the data, this is done becouse if we want to seperate the data in to show witch node is sending what data. So if the nodeNumber plus sensorData (the name of the array) not already there the array is made.
```js
// Initialize the array for this node if it doesn't exist yet
if (!sensorData[nodeNumber]) {
sensorData[nodeNumber] = [];
}
```
For the actual data put in to array function is there a simple array.push for the data that is send allong from when the function is called.

We want only use the last 10 readings from the nodes so there is a check for if the array is longer than 10 the first (or the oldest reading), if that is so there is a .shift executed. This is done to be later used in the graph function. Than there is a call for the next function, that is the updateNodeData and that will acctually find the right html id coresponding with the right reading to update that.

# Graphs
## Introduction
The graphs are used to display the data from the sensors. The data is collected by the raspberry pi and then displayed on the graphs. The graphs are made using the [plotly library](https://plotly.com/javascript/) .
## Requirements
### Live graphs
- Every node has to have a live graph
- The graphs has to be updated every 5 seconds
- All the data from one node has to fit in one graph
## Class diagrams
### Live graphs
```mermaid
classDiagram
class liveGraph {
+nodeId
+cnt
+timeArray
+tempArray
+humiArray
+eco2Array
+tvocArray
makeGraph()
updateGraph()
updateData()
}
```
## Order of operations
### Live graphs
```mermaid

participant Raspberry pi
participant Website
Node->>Raspberry pi: sensordata via websocket every 5 seconds
Raspberry pi->>Website: Node data via websocket if new data is received from the node
Website->>Website: updateGraph()
Website->>Website: updateData()
```
1. Every node sends its data to the raspberry pi via websocket every 5 seconds
2. The raspberry pi sends the data to the website via websocket if new data is received from the node
3. The website updates the data coming from the raspberry pi on its own variables and arrays
4. The website updates the live graphs every time new data is received from the websocket

From yesterday's standup, Sietse made a digital PCD schematic, Dano and Bram made great progress with connecting the PI to the html website and are trying to finish it today. Sam has made progress with documentation and was helping Sietse.
Today we are going to continue our tasks and try to finish these, so we can continue with our project.

5 - 3 - 2024: {
At the standup we discussed our goals for today, Sam is going to get the screen going, Sietse is gonna help Sam, Dano is working on kthe website, and Bram is going to send live info to the database in linux.
}
6 - 3 - 2024 {
Sietse is going to make a class wich contains all the graphs, Dano is making documentation and OOP, Sam is also making OOP,
and im going to continue with working on the connection between the websocket and the database. }
7 - 3 - 2024 {
Sietse is going to make more progress on updating the graph on the website.
Sam is going to finish the code for the big questionaire screen.
Dano is going to be writing some documentation and will be working with classes in arduino.
Bram will do research on python to finish the connection to the database and the websocket.
