4. Case Study – SIOTAS
We would like to build a sensor network for the elders.
A gateway device is used to collect data from node devices by using Zigbee.
All the sensing data will be sent to a server and recorded in database.
We can use a browser to monitor the history of data and graphs.

5. Sensor Devices of SIOTAS
We use STM32F207 as the base of each device.
Gateway Device
Collect all the data from other sensors, and send them to the server.
Lighting Device
Detect the current value of temperature and luminance flux, and turn on the light when it is dark.
Bathroom Device
Detect the movement of users and record user in/out events.
Entrance Device
Detect the door whether it is open, and record events of user entrance.
User can go indoor/outdoor by using RFID.
Activity Device
Detect the heart beat rate and calories consumption.

26. Basic setup
We’re using two pieces of PTK for this laboratory, one as gateway and the other as device.
We don’t use the upper layer of PTK and we shall remove it from PTK for this laboratory.
Run the Ubuntu VM, and thus the sql-agent and listem_cmd up.
Connect gateway to host system via Ethernet.
Insert ZigBee module to gateway and device, and RTC module to device.
Turn gateway and device on; download project to boards respectively.
Run mCloud-SIOTAS-GW66-AppClient
Press Discover till you get an On-line Machine, and Edit to view its info; Our goal is to have a machine which is alive after pressing Refresh within DB Machine .
Go to add a machine based on the info got above. You can view the existing one as an example.
Hint: Consider mCloud-SIOTAS.sql.
Reset the gateway and then device if you redo these steps; you need to have ‘1’ shown on 7-segment of the gateway after turning on the device before you can do monitoring.
Once it works, visit and now there should be a machine which is alive, too.
Then go to Online Monitoring->Control Panel.

27. Exercise
Try to connect them all together and get a simple sensor network.
The goals are that:
You can monitor the light and temperature on the website.
You can use bathroom device and entrance device in advance.
Tips:
Opening phymyadmin and mCloud within host system is preferred.
Try rebooting the Ubuntu VM after making any change; it may help.
For more information, please refer to documents on the course website.
