The connections are fairly simple.
Arduino 1 wire hub.
Connect the vin pin on the arduino to the 5v power rail on the breadboard the ground pin to a ground pin on the raspberry pi and the usb to the raspberry pi usb.
These exposed wires should then be connected to either k1 or k2 on the relay.
Dq is 1 wire data bus should be connected to a digital pin on microcontroller.
Enough of the theory let s go practical.
Let s hook the ds18b20 up to the arduino.
Wire up the arduino.
Arduino 1 wire generic client slave device sensor.
Onewire slave device emulator with support for up to 32 simultaneous 1wire devices.
Wiring ds18b20 temperature sensor to arduino.
Gnd is a ground pin.
Arduino raspberry pi usb jumper wires breadboard.
Add power for raspberry pi.
Arduino create simplifies building a project as a whole without having to switch between different tools to manage all the aspects of whatever you re making.
Interested in one wire.
Vdd pin supplies power for the sensor which can be between 3 3 to 5v.
Please read the introduction and step 2 of my instructable about how to build an arduino 1 wire display 144 chars in order to get more information about the situation and libraries available.
Secondly the hot or line wire usually black should be cut and the ends striped 1 2 of an inch back.

Each sensor has a unique 64 bit serial number etched into it allows for a huge number of sensors to be used on one data bus.
As explained there we will use the onewire hub library.
