Things used in this project

Hardware components

Raspberry Pi 2 Model B

Used as SensorHub host. Collect device data via I2C interface and publish sensor's measurement via AllJoyn

SparkFun Weather Shield

Used as easy to install set of sensors Temperature, Humidity and Pressure. More sensors coming via A2D extension.

Power supply (5V 1.2A)

16GB SD Card (preferable SanDisk Class 10)

Ribbon cable (7 wires, male -> female)

Software apps and online services

Microsoft Windows 10 IoT Core

Windows universal App allow track sensors via AllJoyn from Rpi2, Tablet, desktop and phone.

AllJoyn

Story

There is an existing hands-on-lab "IoT Weather Station using Windows 10"However proposed solution works only if you connect your Rpi2 to TV or display.
It's much easy to leave your hub somewhere and watch Sensors data on remotely Windows 10 device of your choice via AllJoyn and WiFi.

Also if you have many sensors with different measurement, you can automatically discover all of them, collect and aggregate data into a single application screen.

Main asset of this project is software.
There are two solutions published:
SensorHub - is C++ headless application implemented AllJoyn Device System Bridge for sensors. You should compile and upload it into you Rpi2.
This application expose sensor data via AllJoyn. You can see via AllJoyn Explorer how this works immediately.

SensorClient - is C# headed UAP application runs on Windows 10 (phone and desktop) to demonstrated how data from sensor can be displayed anywhere via WiFi. This application use interfaces generated via AllJoynCodeGen.htm

This application is a good start how to use AllJoyn not only to display data but also to send telemetry from local proximity into the Cloud.
