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. 

Order Code : RDL/PVA/13/001/V1.0 

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.

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.

Machine vision (system vision) it’s a apply computer vision in day to day life. While computer vision is focused mainly on image processing at the level of hardware, machine vision most often requires the use of additional hardware I/Oand computer networks to transmit information generated by the other process components. In vision based security system a camera is used to monitor a chamber. Image processing is applied to the acquired frame, and determined whether a security alert is required or not.

The embedded Bluetooth technology, they form a network in which appliances can communicate with each other. This wireless technology is, especially useful in home environment. The smart phones Bluetooth connection is connected to personal computer or laptop, the Window GUI will be act as a server to forward or transmit any data from/to the smart phone and main control board. Depending on the data home appliances control via Bluetooth.

The board uses BTA12-600B, Triac suitable for general purpose mains power AC switching. They can be used as ON/OFF function in applications such as static relays, heating regulation or induction motor starting circuit. They are also recommended for phase control operations in light dimmers and appliance motors speed controllers.
