WIRELESS SENSOR NETWORK FOR CONTINUOUS MONITORING WEATHER IN THE ENVIRONMENT USING ZIGBEE

This Research paper presents a wireless Sensor network (WSN) for continuous Monitoring weather in the environment using Zigbee. The objectives of the current study are for studying the effectiveness of Wireless Sensor Network (WSN) using Zigbee& to study the abnormal conditionof theweather continuously through this Wireless Sensor Network using Zigbee to take appropriate remedial measure.Weather sensor is used to measure weather condition in the environment using Zigbee. 1 st a proper sensor has to be selected for converting the sensed signals (which are electrical signals) in the form of analog signals. The analog signals have to be converted into digital signals by using a proper circuit. The digital signals are feed into the Peripheral Interface Controller (PIC) & its succeeding output is linked to the serial communication circuit. The serial communication circuit’s output is feed into the Zigbee device & this Zigbee device’s output is transmitted through transmitting antenna. In the receiver region, the above transmitted signal is received via the receiving antenna & passed into the Zigbee unit. Output of this Zigbee unit is passed into the RS-232 serial port communication interface & output of this RS-232 is passed into Personal Computer (PC) & sends Global System for Mobile communication (GSM) short message to the receiver. This receiver can utilize the PC or Personal Digital Assistant (PDA) to watch the sensed signals in the remote place. The PIC microcontrollers are supported with a full range of hardware & software development tools. The transmission section codes utilizing different software to function the transmission of sensed digital signals and software to operate the received signals were established. Since, Zigbee has lower power consumption the same is generally used for 24 hours monitor utilizing different soft wares to function the transmission of sensed digital signals and software to operate the received signals were established. Since, Zigbee has lower power consumption the same is generally used for 24 hours monitor of communication transmission system. In particular, when measured signals are over the standard value, the personal computer sends GSM short message to the pollution forecaster’s mobile phone i.e., when there was an abnormality in weather, automatically a call is dialed to the weather forecaster. Also, weather signalare observed in the PC or PDA. Accordingly, appropriate remedial measures are taken.
