LCD stands for Liquid Crystal Display. LCD is finding wide spread use replacing LEDs (seven segment LEDs or other multi segment LEDs) because of the the ability to display numbers, characters and graphics. This is in contrast to LEDs, which are limited to numbers and a few characters.

The board has only one relay driven by TTL circuit . The board works on 12V but the input signal can come directly from microcontroller output working at 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

Real Time Clock based on most popular RTC IC DS1307 which can maintain clock & calendar information. Life of 3V battery is 10 years which maintains accurate clock even without any external power. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The Interface to board is simple I2C with SCK and SDA pins which can be interfaced with any microcontroller easily.

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.

secure low cost Automatic Meter Reading (AMR) system that calculates and transmits the total electrical energy consumption to main server using General Packet Radio Service (GPRS) technology provided by GSM networks. The proposed AMR system consists of three main parts: Accurate digital meter, a transmission facility and the billing server. To make affordable AMR system a low cost off-the-shelf materials are used.

The regulated power supply accepts unregulated intputs from 12V to 15V AC or DC and gives regulated output of 3.3V 5V and 12V suitable for projects which needs precise voltage to work. The input can come from step down transformer. Since board has diode bridge input polarity does not matter.All outputs are brought to screw terminal. There is also an unregulated output voltage to drive high current loads like relays and motors.

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.

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.
