WK339 www.wineyard.in TECHNICAL SPECIFICATIONS: Title of the project : ZigBee based wireless weather station monitoring system Domain : Software : Embedded C, Keil Microcontroller : AT89S52 Power Supply : +5V, 500mA Regulated Power Supply. Crystal : 11.0592MHz for MCU Technical support : M/S Wine Yard Technologies Phone : 040-6464 6363, www.WineYard.in Embedded Systems Design Hyderabad: Tarakarama Estates, 2nd Left Lane – Opp. RS Brothers, Ameerpet, Hyderabad-500073 www.WineYard.in Ph.: 040-6464 6363, 6625 6695, 888 5555 212 ZIGBEE BASED WIRELESS WEATHER STATION MONITORING SYSTEM WK339 www.wineyard.in 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 Hyderabad: Tarakarama Estates, 2nd Left Lane – Opp. RS Brothers, Ameerpet, Hyderabad-500073 www.WineYard.in Ph.: 040-6464 6363, 6625 6695, 888 5555 212 Zigbee based wireless weather station monitoring system WK339 www.wineyard.in 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.

Execution of the System is faster since we are using AT89S52 8-bit microcontroller Detection of the Temperature conditions will help us to avoid damages. Scopes for Advancements: This system is developed for monitoring weather for reporting application only. It also can be controlled by using controller at the receiver side, Applications: Weather Reporting System. Industrial Applications.
