Monitoring and Reporting of Traffic Rules Violation Using Microcontroller through Wireless Communication System

      A system for monitoring and reporting incidences of red light violations at the traffic intersection is presented in this paper. A model of the proposed system has been built and verified experimentally. The system comprises an infrared (IR) transmitter and a receiver unit for detection of red light violation, whereas for identifying the vehicle breaking the law, microcontroller triggered wireless mobile communication network is used. The microcontroller is programmed automatically send a message containing the car license no, date and time of breaking the rule to the numbers of traffic control units stored previously to the cell phone directory. Upon detection of the offender, the corresponding action can be performed by the traffic monitoring system. The proposed system is simple, cheap, reliable, and exempted from the effects of bad weather conditions, improper lightings, etc. and thus more suitable for the detection of a violating vehicle.

Red Light Violation Detection Using RFID

    Traffic lights play an imperative role in traffic management. Traffic lights play an important role in the traffic management. Existing Automatic Traffic Light Violation Detection System is based on the camera’s to detect the violator. This system has a number of limitations like blurry image due to motion , poor image resolution because the number plate is far away, poor lightening, different fonts . The proposed system improves the accuracy of Automatic Traffic Light Violation Detection system as well as helps to trace out the stolen vehicles using RFID.

PC Controlled Robot Using Zigbee Wireless Communication

       The Xbee/Xbee-PRO RF Modules are designed to operate within the ZigBee protocol and support the unique needs of low-cost, low-power wireless sensor networks. The modules require minimal power and provide reliable delivery of data between remote devices. The modules operate within the ISM 2.4 GHz frequency band Zigbee is a worldwide open standard for wireless radio networks in the monitoring and control fields. The standard was developed by the ZigBee Alliance (an association of international companies) to meet the following principal needs

• low cost
• ultra-low power consumption
• use of unlicensed radio bands
• cheap and easy installation
• flexible and extendable networks
• integrated intelligence for network set-up and message routing

             To control the direction of the robot we are using Xbee modules one as transmitter and the other as receiver. The transmitter is fixed to PC and the receiver is fixed to the robot on the other end. We send signals from PC through the Xbee (transmitter) to the receiver which is in built to the robot.

We can use this process to visually control the robot direction even though we are far away by connecting a camera in front of the robot.

Pc Regimented Defence Android Using Zigbee

  In this project, there are two sections (transmitter & receiver) as shown in the block diagrams. The instructions such as Left, Right etc are processed and are given by the person by operating PC. So based upon input of PC the following output will be seen i.e. left or right. In Transmitter Section, the instructions are delivered to Zigbee transceiver from microcontroller which is connected to the PC.  This information is processed and is sent to the receiver section via wireless.

                       In Receiver Section, the signals from the transmitter section are received by the Zigbee transceiver and send to the controller as input. Controller will process this data and it will control the Robot direction according to the instruction which is given at the transmitter section. Then the Robot will move in that particular direction for the given instruction. Similarly camera directions also controlled.

Intelligent Energy Saving System

            Intelligent Energy Saving System can be used in places like where lighting is very important. The libraries will be well illuminated with many lamps. When people are not present at a reading place the lighting can be made OFF and when they are present, the lighting made ON. All these can be done through by Dimming circuit and PIR sensor. If a person entering to the monitored area, the PIR sensors activates and sense the person, gives to the micro controller. The Infrared energy emitted from the living body is focused by a Fresnel lens segment. Then only the PIR sensor activates. After sensing the person   LDR checks the light intensity of the monitored area, whether it is bright or dark. Depending on the LDR output, the lamp may be ON / OFF by using Dimmer circuit.
          By using this system we can adjust the speed of Fan according to the room temperature measured by Thermostat, which is connected to the micro controller.

             To display the room temperature of PIR mode operation we are using the LCD display. 

Energy Harvesting from Passive Human Power

          Portable equipment's are the first evolution from fixed equipment's to make possible that some day computers are part of our everyday lives. The trends in technology allow the decrease in both size and power consumption of complex digital systems. This decrease in size and power gives rise to the concept of wearable devices in which digital systems are integrated in everyday personal belongings, like clothes, watch, glasses, etc. Power is a limiting factor in this kind of devices. Wearable computers are distributed devices in clothes and therefore the power must be distributed and supplied over the body.Human power is defined as the use of human work for energy generation to power an electronic device. One possible division is to distinguish between active and passive harvesting energy method. The active powering of electronic devices takes place when the user of the electronic product has to do a specific work in order to power the product that otherwise the user would not have done. The passive powering of electronic devices takes places when the user doesn't have to do any task different to the normal tasks associated with the product. The energy is harvested from the user's everyday actions (walking, breathing, body heat, blood pressure, finger motion). Once the power is harvested it must be stored and there are many possibilities (capacitors, rechargeable batteries, etc.)

Finger print recognized passport verification(PIC 16F877A / AVR)

     An accurate Access Control System is critical in a wide range of application domain such as national ID card, electronic commerce, and automated banking. A Biometrics based Access Control System based on her physiological or behavioral characteristics is inherently more reliable and more capable in differentiating between an authorized person and a fraudulent imposter than traditional methods. The objective is to design a fingerprint-based biometric system which is capable of achieving a fully automatic "positive personal identification" with a high level of confidence. This paper is implementation of Minutia based approach to fingerprint recognition. The identified and explored the following issues: (i) feature extraction (ii) image enhancement, (iii) Minutiae matching. An alignment-based minutiae-matching algorithm has been proposed. This algorithm is capable of finding the correspondences between input minutiae and the stored template without resorting to exhaustive search and has the ability to compensate adaptively for the nonlinear deformations and in exact transformations between an input and a template. Each passport user details stored in data base server.
