Wireless Remote Control System

Abstract

This project shows the application of a "smart sensor" in monitoring and controlling remote device via a Zigbee technology. It exploits the "smart sensor" technique in measuring, processing, storing and distributing data to remote terminal. In this project the temperature of a remote system is controlled and observed. The Remote Terminal Unit (RTU) is developed to sample a signal, process, and store and propagate the data to the Handheld Programming Unit (HPU). On top of it, it is designed to independently handle specific control tasks such switching on/off the target application based on the received command by the HPU. While the HPU provides user interface which incorporates display unit and input unit.

Wireless technology has already become an important application which usually integrated to a wide range of device and other technologies. The enhancements provide by the wireless technology gives the ease of control to the users. Nowadays, almost all the electronic devices are equipped with wireless technology. This fact shows the necessity and benefits provide by this technology. This project is mainly concern about home power consumption observation system with wireless capabilities. It is use the Smart sensor as the wireless modules. This project uses two microcontrollers to handle the wireless communication protocol. The first microcontroller done the calculation needed and display it to the user with both hardware and software interface. The second microcontroller functions as the watch guard for the sensor circuit. The received data from sensor circuit is stored and send to the first microcontroller upon request. Moreover, the user interfaces gives ease of controls to the users.
