SENSOR WIRELESS INTERFACE MODULE

In the oil and gas industry, wired sensor network is the traditional and
commonly used. Nowadays, there is a new trend in network communication which is
the wireless sensor network. Hence, the wireless technology is now growing fast and
keeps improving with time. The objectives of this project are to find an economical
wireless solution for the wireless sensor network, design, build and test a short-range
sensor wireless interface module. A lot of study and research in communications and
instrumentation has to be made in order to design the system. The designed system
consists of a RTD transmitter, A/D converters, signal interface, a WiFi Access Point
and a WiFi enabled PC. Based on the surveys conducted in this project, the WiFi
technology is suitable for this project because of its maximum transfer speed,
maximum distance and maximum devices that it can connect at one time. This system
also can reduce maintenance cost and save time.
