  1. TOUCH SCREEN AND ZIGBEE BASED WIRELESS COMMUNICATION ASSISTANT Guided By: Submitted By: XYZ ABC (Roll No.) (Assistant Professor) Year/Sem

  2. Introduction In this project we are using Zigbee and Touch screen Technology to make it easy even to illiterates as it is also included with images, which indicates the needs. This even reduces the difficulty to airhostess in receiving the customers with different languages. Here for wireless communication purpose we use Zigbee technology.

  3. Block diagram:

  4. This project consists of Zigbee based system that transmits the wireless signals according to the input given by the user using touch screen. At the receiver (airhostess) end the information will be displayed on GLCD in English language. The Zigbee technology is broadly adopted for bulk and fast data transmission over a dedicated channel.

  5. Here when user sends his need through touch screen, then micro controller transmits that information through Zigbee transmitter. The information received by the Zigbee receiver will be displayed on GLCD.

  6. This project design can be divided into two sections: Hardware implementations: The hardware implementation consists of the development of the Touch screen sensor, Zigbee and GLCD. Software implementation: Software implementation focuses on the programming of the microcontroller.

  7. Touch Screen Sensor .

  8. Touch screen panel is composed of several layers, the most important of which are two thin, metallic, electrically conductive layers separated by a narrow gap. When an object, such as a finger, presses down on a point on the panel's outer surface the two metallic layers become connected at that point: the panel then behaves as a pair of voltage dividers with connected outputs. This causes a change in the electrical current which is registered as a touch event and sent to the controller for processing

  10. Zigbee Zigbee is a wireless technology developed by Zigbee Alliance as an open global standard to address the unique needs of low-cost, low-power, wireless sensor networks. ZigBee devices transmit data over longer distances ZigBee is used in applications that require a low data rate, long battery life, and secure networking. It is simpler and less expensive than other WPANs, such as Bluetooth or Wi-Fi.

  11. Applications It is used in airlines It is applicable in hospitals It is used in restaurants Very useful even for illiterates. Helpful in abroad to express user’s needs. Deaf and dump people also can interact with others Can be used with any languages.

  12. Expected Outcome As we have different languages in our world and its impossible for us to know all the languages. So, in this project we are building a device that helps them in expressing their needs with other language people. • Its operation is simple and easy • It is less expensive • It is highly efficient • User friendly and easy to install.

  13. Thank You
