Hand vein patterns are unique and universal. Vein pattern is used as biometric feature in recent years. But, it is not very much popular biometric system as compared to other systems like fingerprint, iris etc., because of the higher cost. For conventional algorithm, it is necessary to use high quality images, which demand high-priced collection devices. The two approaches for vein authentication are repeated line tracking and maximum curvature method. Currently we are working on maximum curvature method. Here we are putting forward the new approach for low cost hand dorsa vein pattern acquisition using low cost device and proposing an algorithm to extract features from these low quality images which are used for personal authentication.

In the present IT age, we are in need of fully automated industrial system. To design of Data Acquisition System (DAS) and its control is a challenging part of any measurement, automation and control system applications. Advancement in technology is very well reflected and supported by changes in measurement and control instrumentation. To move to high-speed serial from Parallel bus architectures has become prevalent and among these Ethernet is the most preferred switched Serial bus, which is forward-looking and backward-compatible. Great stride have been made in promoting Ethernet use for industrial networks and factory automation. The Web based distributed measurement and control is slowly replacing parallel architectures due to its non-crate architecture which reduces complexities of cooling, maintenance etc for slow speed field processing. A new kind of expandable, distributed large I/O data acquisition system based on low cost microcontroller based electronic web server boards has been investigated and developed in this paper, whose hardware boards use 8-bit RISC processor with Ethernet controller . There is a great deal of benefits for process plants in adopting the Internet to control systems. Over the years, there has been constant increase in the development of industrial Automation through remote monitoring and diagnosis virtually. By surveying down the existing remote monitoring system used for process plant equipment, this system tends to focus on the recent trends and developments in the control of equipments and devices in the industries by remote monitoring through Internet. The Internet based automation is made possible by the use of Programmable Logic Controller (PLC), Supervisory Control and Data Acquisition (SCADA), Virtual Private Network (VPN) and other network elements.

Digital Soil Moisture Sensor is having triple output mode i.e., Digital output is simple; Analog output is more accurate and Serial output with exact readings. The sensor will detect the moisture of the soil i.e shortage of water contents in the soil and if the contents are low the module output will be high otherwise the out put will remain in neutral condition. This sensor can be used for the automation of the gardening etc.
