Skogsnet   

Temperature and Humidity monitoring.

Concept

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

Dependencies

How to install required dependencies.

sudo pacman -S raylib nlohmann-json base-devel cmake 

Add the current user to the group of the USB device port:

# Show the group
ls -l /dev/ttyACM0
crw-rw---- 1 root uucp 166, 0 Oct 18 21:41 /dev/ttyACM0

# Add the current user to the group
sudo usermod -aG uucp $(whoami)

# Logout -> Login again

Running

How to start both programs.

make -j 2 skogsnet raylibfrontend
