| dc.description.abstract | The problem of global warming, sea levels and climate change to an extreme
is no longer the world's stories, which are direct threats to Vietnam: Floods, droughts, increased storm surges heavier…Directly affect to the safety of people and the economy. Environmental pollution also affects human health and reduces the qualit y
of our land and water. As a result, there is great interest in monitoring water and air quality and ensuring that all areas are compliant with legislation.
The demand that this thesis research will construct a system can connect with ZigBee wireless network nodes for collect and transfer air data as temperature, humidity or water environmental data as salinity, ph, dissolved oxygen, water temperature by data logger, and then data will transfer through the Internet and SMS. By this way people can monitor and observe the changing of climate. Therefore, we can forecast and predict the influence of climate to people. From that, managers can have policy and planning for support people in agriculture and economy. Moreover, we can minimize and prevent consequence of climate change to life.
In this project, I am going to develop a ubiquitous sensor network node to collect environmental information and transmit to climate change monitoring center through Internet or mobile phone network. To carry out this research work, I study internet network protocol, ZigBee stack, design and integrate hardware equipments as Sim300C module, AVR, PIC microcontroller, Enc28j60 Internet driver IC into a compact node, the research also include building the protocols to interface ubiquitous gateway node with Wireless sensor network, send data through Internet and mobile
phone network. | en_US |
