摘要：Generally in industries there are traditional network communications like RS232,RS485,etc. which are limited for shortdistances. Data acquisition based on single chip has limited processing capacity and real time reliability. With development inArm processor, efficient data acquisition and control in various fields can be achieved. Remote I/O data acquisition systemdeveloped in this project measures temperature, humidity, gas using WSN(wireless sensor networks) technology. WIFITechnology is a proficient used by mobiles, workplaces, home an d computer system all around the world. Wifi technology is aspectrum radio technology and OFDM radio technology therefore it is an alternative of wireless LAN. WIFI technology based onthe IEEE 802.11 and wifi technology alliance so we can say that it is a synonym of IEEE802.11.This system is developed usingARM9(S3C2440A) hardware platform combined with WI-FI network. IT consists of two nodes one Transmitter node and oneReceiver node. The transmitter node acquires sensors information ,process data and transmit it through WI-FI to Receiver node.The receiver node receives data from sensors node which is implemented on ARM9,process it and retransmits the controllingsignal information via WI-FI communication and also display the sensor information on PC based GUI implemented using MatLab. The keil IDE software will be used to build the hex file for these C programs.
