Minimal web interface for SDS011 air quality sensor

This application makes use of a SDS011 nova PM Sensor and visualizes air quality levels in a minimalistic web interface. The sensor is queried for new data every 15 minutes, which is then saved in a MongoDB database. Another container runs a light nodejs-Webapp, that displays the data in a simple chartjs graph. The entire application is dockerized. The project is further explained in this Medium article.

Installation & Usage

Linux-based OS (x86 instruction set)

Checkout into the master branch. Run the app as follows:

1. Connect the sensor to your USB-port & ensure that it is accessible under /dev/ttyUSB0 (this is standard for many Linux based systems such as Ubuntu)
2. Run sudo docker-compose up -d (from within the sds011docker directory; optionally omit the -d if you want to see the logging output of the containers)
3. Open a browser and type in "localhost" into the address bar

Raspbian (ARMv6 instruction set)

Checkout into the raspberry branch. Follow instructions there.
