SmoothMove

This README.md serves as an additional technical documentation of the project implemented in the course Design Thinking: Explorative Prototyping. The project revolved around displaying air quality data - measured with MQ Sensors - on a website.

Main communication workflow: Arduino->node.js server->Website

The data is received and parsed in JSON format: {"CO2":10,"CH4":100.2,"SMOKE":10,"TOLUENE":10,"NH4":10,"ACETONE":10,"CO":10,"H2":10,"FG":10}

Prerequisites

• npm installation
• python3 installation
• Arduino Nano with relevant sensors (MQ-Sensor-Series) - provided
• Installation of Arduino IDE
• git clone https://github.com/juliastic/SmoothMove-Project.git

Setup Arduino

• Connect Arduino Nano to computer with relevant sensors
• Within Arduino IDE:
  • Install library MQUnifiedsensor to allow the arduino to read MQ Sensor references
  • Install library DHT sensor library if DHT11, DHT22, etc. sensors get used to measure Temperature & Humidity
  • Optional: Install according library for displays if one is used, depending on the display
• cd AirQualitySensorProject
• Uncomment calibration code (AirQualitySensorProject.ino lines 63-104) & calibrate sensors for 30min
• Comment calibration code again

Setup Website

• cd SmoothMoveWebsite
• npm install
• Change ip address based on your local ip address in js/measurementsHandler.js, server/server.py & server/app.js (see also comments)

Run Project

Please note that the Arduino needs to be started first, the server/app.js needs to be started within 15s of starting the Arduino in order for the initial data to arrive!

• ARDUINO
  • Run code within IDE
• Website
  • Execute:
    • node server/app.js
    • python3 server/server.py
  • Visit IP_ADDRESS:8000

Testing Project with Dummy Data

This does not require the Arduino setup!

To test the website with dummy data:

• All the relevant parsing code should be commented in server/app.js
• Optional: Variable lastData can be modified
• Execute:
  • node server/app.js
  • python3 server/server.py
