ZIGBEE is one of the most widely used transceiver standard in wireless sensor networks. Zigbee over IEEE 802.15.4., defines specifications for low rate WPAN(LR-WPAN) to support lower monitoring and controlling devices. Zigbee is developed by Zigbee alliance,which has hundreds of member companies

Abstract — In this paper we propose a system that takes atten-dance of student and maintaining its records in an academic institute automatically. Manually taking the attendance and maintaining it for a long time makes it difficult task as well as wastes a lot of time. For this reason an efficient system is de-signed. This system takes attendance with the help of a finger-print sensor module and all the records are saved on a computer. Fingerprint sensor module and LCD screen are dynamic which can move in the room. In order to mark the attendance, student has to place his/her finger on the fingerprint sensor module. On identification of particular student, his attendance record is up-dated in the database and he/she is notified through LCD screen. In this system we are going to generate Microsoft excel atten-dance report on computer. This report will generate automatical-ly after 15 days (depends upon user). This report will be sent to the respected HOD, teacher and student’s parents email Id.

This paper elucidates the concept and development of Zigbee technology which is IEEE standard 802.15.4 in dish ordering systems in hotels. This paper has shown the concept of an automatic self ordering system directly given to the chefs by the customer. The real time ordered data is send wirelessly

In the next few years, the home energy management system trend of the smart home will become increasingly evident. From the application and development of recent years, the Bluetooth and Zigbee are the most valued by the industry. Of these two kinds of technology, Zigbee supports low cost and more

ABSTRACT A networked wireless AMR (automatic meter reading) system based on wireless sensor networks and ZigBee technology is presented in this paper for solving the problems existed in the existing meter reading system. An AMR system based on CC2420 is designed. The hardware structure of system

802.15.4 Medium Access Control (MAC) and Physical Layer (PHY) wireless standard. It employs a suite of technologies to enable scalable, self-organizing, self-healing networks that can manage various data traffic patterns. ZigBee is a low-cost, low-power, wireless mesh networking standard. The low cost

Abstract-In this paper, a solution of remote background radiation monitoring, based on the concept of Wireless Sensor Network (WSN), is presented. Radiation dose rate measured by the sensor node is sent to the monitoring station through ZigBee wireless network operated on 2.4 GHz unlicensed

on an hourly and daily basis. This historical data can be pulled up on the display at the request of the user. Various techniques are used to monitor the weather like satellites, radars, microcontrollers and many other simple instruments. Weather can also be monitored by using remote wireless sensors. Zigbee

for handling sensors, power back-up, real time clock and data communication module which based on ZigBee protocol. Sensors, including a Resistance Temperature Detector (RTD) and a Liquid level sensor performs according to manufacturers' specifications are calibrated and tested using LabVIEW software

such as water pumping for crops or river life stock. Zigbee technology is renewable and is still a new concept. A Zigbee based water pumping system comprises of various components like, PV panels, pumps and Zigbee modules. In this Zigbee technology is used for wireless transmission and for enhancing
