Introduce new way how to use 1wire temperature sensors
Step 1: UniPi Connection
UniPi board includes 1wire master microchip.
There is new type of 1 wire sensors which are made with 4 fiber cable.
Position in RJ45 connector:
6- Data UP
7- Data Down
In this case you can connect all temperature in a row.
Up to 20 temperature sensors or up to 360 meters.
Step 2: How to Connect 1wire Sensors to UniPi Board
It' s easy to make hardware hub for this type of connection.
Step 3: Use RRD to Print All Temperature Sensors
With RRD you can make your own graphs.
