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.

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.

Server Side of SIOTAS
We would establish LAMP environment. LAMP means Linux, Apache, MySQL, and PHP.
Create a website for monitoring and analyzing. Design a database for data captured by sensors.

Table Schemas
data_block This is used to record continuous data. Data will store into a file and record the filename in database.
data_feed This is used to record intermittent data. The data will be stored into value defined by the schema.
For detailed description, please refer to the document.
