Tracks the busyness of the SCE club room using ESP32s and sound sensors.

SmartNoiseSense

Using ESP32s, sound sensors and Google Cloud Platform, this project tracks the noise levels of the Software and Computer Engineering Society's club room.

Project Folder Description

The project is split into three folders, GoogleCloud SoundRead and StudentWebsite.

• GoogleCloud: Contains the code for the functions that are executed in the cloud to handle published messages.
• SoundRead: Holds all of the code that is flashed onto the ESP32 to read noise and publish the data to a Google PubSub topic.
• StudentWebsite: Holds all of the website code, written using React.js, to read the room's current noise level and past readings.

To Run the Student Website

1. Install Node.js

• You can verify the installation by entering node --version in your terminal

2. With node installed, clone this repository with git clone https://github.com/evanugarte/SmartNoiseSense or download the .zip file
3. Enter the directory with cd SmartNoiseSense/StudentWebsite
4. Install dependencies with npm install
5. Run the website with npm run start

smartnoisesense's Issues

Improve Sound Reading by Sending Average

Instead of sending an instantaneous sound reading ever minute, we should take an average for the sound reading, and send the average to the PubSub topic.

Use FreeRTOS to Publish Sound Data to GoogleCloud

Instead of using Arduino IDE, I switch to Embedded C and FreeRTOS to connect to Google Cloud.

Write code for ESP32s to Read Sound Data

Using analogRead(A0) with the arduino library, we should be able to have the ESP32s read from the Envelope gate of the SparkFun Sound Sensor

Have Sound Data Return Loudness Separated by Area

In the function getSoundData for our firebase query file, logic should be added in the forEach loop which goes through all the documents.

• Check location of sound
• Use case statements to add the sound to an object of each corner
  • This object should have a field that is location string?
  • This object should have a field called sound that will be averaged
  • This object should have a field called timesRead that will count how many readings from that corner were read
• We should then return an object that has 4 fields, which is can be
  • nwAvg, neAvg, swAvg, and seAvg

We will then be able to access this object on the UI side and show the heatmap based on each Avg field.

Fix Cloud Function to handle Init Messages

This involves fixing CloudFunction.js. If we don't get a sound value then we know the message shouldn't be published. To fix this bug an if statement must be added to accommodate this case.

Create Heat Map on Website for Room

This should be a simple react component to show how loud each of the corners of the room are on a daily basis.

Show Current Loudness in SCE Room

This can simply be an output that takes the most recent values written to firestore and relays them for users to see.

Create Website to Visualize Sound Values

Using React.js, a website will be made that will watch the status of the firestore data being updated. This website can then use that data to present it to a user to help them see how loud the room is.

Solder Pins to Sound Sensors

Create Google Cloud Project

Using Google Cloud Platform, set up a project that we can have a device registry, PubSub topic, and cloud function to use.

Add Location Handling to Cloud Function

Cloud function should take the sensors location and data into account and publish it to firestore.

Modify Y Axis on Website Graph

The y axis at the moment doesn't reflect good values. We can make the sound range from 80 - 200, which is what most averages come out to be.

Add Cloud Function to Handle Topic Publish

This cloud function should take a message's value and add it to firestore for sound to be logged.
