A relay can be used for controlling a high-voltage circuit with a low-voltage signal, as in some low voltage digital controls where we can control a larger output switching circuitry.

Few older devices use DB9 connectors, but most modern computers use USB  port for data transfer. By using a USB to serial adapter, you can continue to use your older serial-enabled device through your new computer's USB port.

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.

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.

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.

Pull-up resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels, if external devices are disconnected or high-impedance is introduced. They may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages.A pull-up resistor weakly "pulls" the voltage of the wire it is connected to towards its voltage source level when the other components on the line are inactive.

Sensors are the hopeful device for precision agriculture. By forming wireless sensor network we can make good monitoring system in the paddy crop field area. This project proposed idea about monitoring the crop field area without man power. The fundamental concept of this project is to provide a highly enabled monitoring of crop field. In this all the different sensor values such as ph sensor, temperature sensor, moisture sensor sends value through gprs and the values are sensed and processed and if any of the sensor value exceeds the minimum or maximum value, a alarm is activated and the farmer gets a message on his phone and also a email message.
