ABSTRACT:
In an industry during certain hazards is will be very difficult to monitor the
parameter through wires and analog devices such as transducers. To overcome this
problem we use wireless device to monitor the parameters so that we can take certain
steps even in worst case. Few years back the use of wireless device was very less, but due
the rapid development is technology now-a-days we use maximum of our data transfer
through wireless like Wi-Fi, Bluetooth, Wi Max, etc.
The fundamental aim of this project is to develop an embedded system to design a
wireless weather monitoring system which enables to monitor the weather parameter in
an industry or anywhere by using Zigbee technology and display the parameter on the
PC’s screen using visual basic.
The system contains two parts. One is transmitter node and another one is receiver part
and both can be any number. The transmitter part consists of whether sensors,
microcontroller and ZigBee and the receiver part consist of a PC interfaced with Zigbee
through PC serial port. In this project we deal with monitoring the weather related
parameters through wireless Zigbee modules. Here we monitor temperature, wind speed,
wind direction and humidity with the help of respective sensors. The data from the
sensors are collected by the micro controller and transmitted to the receiver section
through wireless medium. All the parameters are viewed by the pc using visual basic
program in the receiver side.
In view of all this things, the design of wireless parameter progress helps in
an industry to monitor the parameter in real time with the use of zigbee, is an easy
installation platform, cost effective method for the low bit rate transmission, so with the

help of the ready zigbee platform by using the embedded c language we interface the
module with the pc by the help of visual basic we monitor the parameters in the system.
analog device may be damaged may be during the fire accidents, etc. But with the
wireless transmission we have not have an accurate data but when compared to the
analog failure the errors are very minimum so we use wireless to monitor the parameter
in an industry where their no means of human interface to monitor the parameters.
In this project we deal to monitor the parameter through wireless by using zigbee
ready platform which is based on the IEEE 802.15.4, 2.4 GHz, in this module we use
MSP 430 for the voltage and other technical parameters, which has in build RAM in it.
The working of this module is simple in principle, the changes in certain place is monitor
in real time process which is very accurate in monitoring and their no other interface and
other disturbance in monitoring the parameter in this project we monitor temperature and
humidity with the help of respective sensors. The change in the room temperature,
humidity can be monitored like real time as the change is displayed in respective interval
in the visual basic screen.
In this project we are using AT89S52 microcontroller. We interface the
microcontroller with zigbee module to monitor the weather station from the remote area.
This project uses power supply i.e regulated 5V for modules and microcontroller.
7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave
rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
