Temperature and Humidity monitoring.
Using a I2C Grove Sensor, you can transmit
temperature / humidity data with a Arduino
MKR1010 Wifi
board.
The Arduino sends the data through Serial USB
to the host, where the program skogsnet.cpp
reads the serial stream and parses the JSON data.
This data can then be used as inputs to some
logic, a PID regulator implementation perhaps.
The data received by the skogsnet program is written out to output.dat
How to install required dependencies.
sudo pacman -S raylib nlohmann-json base-devel cmake How to start both programs.
