System statistics of Raspberry Pi

The flow reads and presents system details and statistics of Raspberry Pi (RasPi, RPi). Tested on RasPi 1 mode B and RasPi 3 mode B. The flow has 3 groups respectively:

1. CPU (Current load + temperature, graphs of load and temperature).
2. RAM (Currently used, use history graph).
3. Storage / SD-card (Currently used, graph of total, free and used).

The data refreshes every 5 minutes.

Required OS nodes:

npm install node-red-contrib-os
