The goal of this project is a program that takes data from CO2 meter and plots it in real time to a graph
This project works with this device:
UI example:
Keep in mind that this project depends on CO2mon binary, so the most reliable
675C
method
of installation implies building CO2mon on your machine and putting resulting binary to
./src/server/modules/co2-sensor-data-stream/lib/.
Good news is that this repo already has bundled binary in it, so all you need is to do following steps:
brew install hidapi(this is a part of installation process of CO2mon)git clone https://github.com/antipin/co2-monitor.gitcd ./co2-monitornpm installnpm run build-servernpm run build-clientnpm run start(or, if you need sudoNODE_ENV=production sudo node ./dist/server/bin/app.js)http://localhost:8001
If there are any errors concerning lack of some library, I guess you should build CO2mon by yourself and replace bundled binary with builded one.
If you have issues on RaspberryPi, try to run app with sudo by:
NODE_ENV=production sudo node ./dist/server/bin/app.js command.
If yo see the following error
co2-sensor-data-stream.ERROR: /home/pi/co2-monitor/dist/server/modules/co2-sensor-data-stream/lib/co2mond: 1: /home/pi/co2-monitor/dist/server/modules/co2-sensor-data-stream/lib/co2mond: Syntax error: "(" unexpected
