NB: The temperature reading from DHT11 takes some time to change, and so the video has been edited to reduce the duration between each reading change

Project Description

A beautiful flawless project that plays melodies according to the subjected temperature 😉

The Problem (that doesn't exist)

Nobody likes to sense the surrounding temperature by themselves, do they? So, we made this complicated facade to help you with that 😌

The Solution (that nobody asked for)

We collect data from a temperature sensor and play accurate melodies for you 🎶

Technical Details

Technologies/Components Used

For Software:

• Languages used:
  • Javascript
  • CPP
• Framework ysed:
  • Arduino
  • Node.JS
• Libraries used:
  • Server side: Audic, ws
  • Hardware side: dht11, ESP8266WiFi, WiFiClient
• Tools used:
  • Code Editors: Arduino IDE & Zed
  • Sound editing: Audacity

For Hardware:

• Components:
  • NodeMCU v1 (ESP8266)
  • DHT11 temperature sensor

Implementation

1. Read data from DHT11 sensor
2. Send the data to ntfy
3. On the PC, establish a web socket to ntfy api.
4. Checking the temperatures, and playing specified audio files

Installation

Firstly, copy the repo to your local machine:

git clone https://github.com/Ranger-NF/Thaapasakhi/
cd Thaapasakhi

Now, there are 2 parts to this repo/project: Server (src/server) and NodeMCU (src/microcontroller). Follow the following steps for each component:

• Server:

cd src/server
npm install

• NodeMCU:

  • Open src/mircrocontroller/main/main.ino file in Arduino IDE

  • Enter missing details:

    1. Enter your Wifi SSID & Password in main.ino (line 5 & 6):

    const char* SSID = "<ENTER_WIFI_SSID>"; // File: src/microcontrollers/main/main.ino
    const char* password = "<ENTER_WIFI_PASSWORD>";
    

    2. Create a topic over at ntfy and enter the topic name in main.ino (line 76):

      String url = "/<ENTER_TOPIC_NAME>"; // File: src/microcontrollers/main/main.ino
    

  • Connect NodeMCU board and upload the code

Run

• Server:

  cd src/server
  node index.js
  

• NodeMCU: Just connect it to power

Diagrams

There are 3 parts: Microcontroller, Server(ntfy) and your PC(Node.js web server)

Schematic & Circuit

GND(Ground) pin is connected to GND, VDD pin is connected to 3.3v and Signal pin is connected to D2 of NodeMCU
