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. 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, LDR 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 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 were we monitor the parameters in the system.

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 light intensity, 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. The LPC2148 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation and embedded trace support, together with 128/512 kilobytes of embedded high speed flash memory. A 128-bit wide memory interface and unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb Mode reduces code by more than 30% with minimal performance penalty. With their compact 64 pin package, low power consumption, various 32-bit timers, 4- channel 10-bit ADC, USB PORT,PWM channels and 46 GPIO lines with up to 9 external interrupt pins these microcontrollers are particularly suitable for industrial control, medical systems, access control and point-ofsale. With a wide range of serial communications interfaces, they are also very well suited for communication gateways, protocol converters and embedded soft modems as well as many other general-purpose applications. This project uses two power supplies, one is regulated 5V for modules and other one is 3.3V for 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.
