NodeJS program for visualizing bme-280 sensor data. Meant for use with raspberry-pi.
The server can be started with:
npm install && node index.js
After that it starts reading sensor data and writes it to sensor_log.json from which it's being passed to front-end. The front-end is accessible from port 3001.
To keep the program running in the background one can use pm2 or something similar. Inside project folder run:
npm install -g pm2 && npm install && pm2 start index.js
Config can be found in config.js and contains following options:
| NAME | DEFAULT | DESCRIPTION |
