Global industrial monitoring through wireless communication using ARM-7

Abstract

      The Aim of the project is to collect data from different sensors using ARM-7 and Zigbee communication system This paper proposes an advanced system for process management via a ARM-7 based multi parameter monitoring hardware system designed using RS232 and microcontroller that measures and controls various global parameters. The system comprises of a single master and multiple slaves with wireless mode of communication. The parameters that can be tracked are voltage, temperature and light intensity. Here RF can provide a communication between sensor node and monitoring node. In this design we can overcome the drawback of existing system. Here we can monitor the above parameters and based on the condition we can also control the parameters. In existing system we are using RF, By using RF it gives less distance, instead of this RF communication we are using zigbee communication for longer distance.. The hardware design contains ARM-7 Microcontroller, LCD, Relay, DC fan, Buzzer X-bee transceiver, Voltage sensor , temperature sensor (LM35) , LDR. Here the Raspberry pi can continuously taking the data from the sensors and send it to the monitoring section through X-bee transceiver and the data will display on the LCD. If any parameter exceeds the limit then the microcontroller can control the controlling device (the controlling devices are buzzer, DC fan and Load). Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. One of the main advantages of this ZIGBEE communication is that it provides a noise free communication, the amount of noise added in this type of communication is very less compared to the other wireless communications.
