THE WIRELESS NETWORK FOR HOME CARE SYSTEM USING ZIGBEE

   Security is primary concern for every one. There are many ways to provide security at homes or in industries. But what if the security is assured irrespective of the person is inside or outside the house. This Project describes a design of effective security alarm system that can monitor an industry or house with different sensors using Zigbee Technology.

       Zigbee   is a specification for a suite of high level communication protocols using small, low-power digital radios based on the IEEE 802.15.4-2003 standard for wireless personal area networks (WPANs), such as wireless headphones connecting with cell phones via short-range radio. The technology defined by the Zigbee specification is intended to be simpler and less expensive than other WPANs, such as Bluetooth. Zigbee is targeted at radio frequency (RF) applications that require a low data rate, long battery life, and secure networking.

Wireless Security System is a security system using Zigbee monitors the status of each sensor at the transmitter side and displays this status at the receiver end. This project is mainly useful in homes, industries etc to continuously safeguard homes and industries. The status of these different sensors can be monitored continuously and this status is transmitted using Zigbee Transmitter. The response of these sensors is read at the receiver end. Whenever any of the sensors is triggered or activated, the response can be identified at the receiver side using LED indication and also on the LCD display and also the burglar alarm will be activated.

Thus, when anything goes wrong at the transmitter side, the same will be transmitted and received at the receiver side and the burglar alarm will be activated to alert the neighbours and at the same time, autodialing action will be carried on. The system dials to the number already stored in the system. Thus, the person associated with this system receives the call from the system and can proceed with the necessary action.
