Implementation of Wireless Sensor Networks Using ZigBee
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 11
Abstract
WSNs are usually composed of small, low cost devices that communicate wirelessly and have the capabilities of processing, sensing and storing. A sensor network consists of an array of numerous sensor networks of diverse types interconnected by a wireless communication network. The system extracts relevant information from the available data. Sensor data is shared between these sensor nodes and used as input to a distributed estimation system. This data is then forwarded via internet or other gateways to the user where the next course of action will be decided. The project proposes the use of sensor networks programmed on Arduino and use of ZigBee routers to wirelessly sense and transmits data respectively, from a remote inaccessible area or fields where human intervention is to be minimized. The main aim is to track or sense a particular parameter such as temperature, pressure, gas leakage etc and relay the data to a control center where necessary corrective action may be taken. ZigBee routers interfaced with LCD display can be used to continuously monitor and display the parameters sensed. The data received at the receiver end can also be logged into a computer with time stamps for future references. A GSM module can be used to broadcast a message or alert sent from the controller or the mother node to the mobile numbers of the concerned authorities and people in potential danger so necessary corrective action may be taken. The proposed model can work as an alert system, sensing a parameter and on encountering an abnormality can relay an alert via the ZigBee network. The procedure is that that the temperature and the gas sensors interfaced to the mother (transmitter side) Arduino board located at a distant place where the parameters need to be sensed, will continuously sense the surrounding temperatures and air for traces of LPG and other inflammable gases and will continuously transmit the sensed temperatures via the ZigBee module interfaced to the mother Arduino board to the other ZigBee module interfaced to a serial LCD display via Arduino. The GSM shield interfaced on the transmitting side will send alert SMS to the pre-fed phone numbers when the parameters will exceed a certain pre-defined value.
