Wireless Microcontroller Based Mutlidrop System

Abstract

In our daily life, Wireless based industrial automation is a prime concern. The field of approach to Zigbee Based Wireless Network for Industrial Applications has been standardized now a days. A wireless control and monitoring system for a industrial machines realized using the Zigbee communication protocol for safe and economic data communication in industrial fields where the wired communication is either more expensive or impossible due to physical conditions. The machines can be controlled wireless due to the microcontroller interface developed with Zigbee. It is also possible to protect the machines against some critical conditions such as change in temperature, humidity, light, pressure etc. so controlling, monitoring, and protection of the system are realized in real time. So the wireless communication technology is used in this paper, controlling abilities of the system are increased and also hardware and the necessities of other similar equipment for data communication are minimized.

We concerns with designing and implementing the system which can be utilized effectively to reduce human efforts and accuracy of measurement of data. The main work behind this is to make instrumentation system more power full by enabling it modern communication technologies. Here we are using different sensors like temperature and humidity to measure surrounding temperature and humidity. LCD is used to display current and set parameters. The total controlling action done by microcontroller, which is heart of the system and for wireless data transmission Zigbee module is used.
