GPS BASED BORDER ALERT SYSTEM FOR FISHERMEN WITH BOAT SPEEDOMETER


In this modern, fast moving and insecure world, it is become a basic necessity to be aware of one’s safety. Maximum risks occur for fishermen in situations where they travel on a boat for fishing. In some situations they should not move after some point and they should not enter into other countries area. There is a real necessity in designing a system that can track the vehicle and send the information about the vehicle to the concerned person and alert the fishermen also.

The system that a function as a tracking and a security system has been designed that uses main underlying concept which is GPS (Global Positioning System). This system can deal with both place and security. The VMSS (Vehicle Monitoring and Security System) is a GPS based vehicle tracking system that is used for security applications as well.

The main application of this system is tracking the vehicle to which the GPS is connected, giving the information about its position whenever required and for the security of each person travelling by the vehicle. This is done with the help of the GPS satellite and the GPS module attached to the vehicle which needs to be tracked.

The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day.

The GPS antenna present in the GPS module receives the information from the GPS satellite and it reveals the position information. This information received from the GPS antenna is sent to the controlling station where it is decoded. Thus, the complete data related to the vehicle is available at the controlling unit.
This information is sent to the owner or to the concerned person continuously using a GPS modem. This GPS modem has an antenna too. The information about the vehicle can also be displayed on LCD. If the person crosses the boarder then he checks the data coming from GPS and he alerted.


WIRELESS DATA LOGGER USING RF COMMUNICATION

The project deals with the design and development of hardware and software for eight channel data logger system. A data logger (also datalogger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or by using external instruments and sensors. One of the primary advantages of using these data loggers is the ability to automatically and continuously collect data on a 24-hour basis.
The data which are recorded continuously in this project are Temperature, Intensity and Humidity. These analog quantities are taken and converted into corresponding digital values using an eight channel ADC. These converted digital values are transmitted from the microcontroller using RF transmitter and an encoder. These values are received at the receiver end using RF receiver and a decoder.

The RF modules used here are 2.4 GHz. The processed data from ADC is sent to microcontroller. The microcontroller passes this data to the RF transmitter. At the receiving end, the RF receiver receives this data, gives it in the single bit data into 8-bit data and presents it to the microcontroller. Now, it is the job of the controller to read the data and display the same data on LCD.


WEATHER MONITORING SYSTEM IN REMOTE PLACES USING GSM


The objective of this project is to develop a weather monitoring system and monitor the parameters like temperature, humidity, light intensity etc in remote places. Different sensors are used for different parameter measurement. Since all the sensors outputs analog values, these analog values has to be converted into digital data and should be presented to the controlling for further processing.

ADC is used to convert these analog parameters into digital values. These digital values are then passed to the controller. This controller will be interfaced with the GSM modem. All this arrangement will be fixed at a place in remote area and the processed data will be sent to the user mobile who is actually monitoring this unit. This is all done with the help of wireless concept, GSM. The parameters are also displayed on the LCD.

ABSTRACT

MULTI USER GSM BASED DIGITAL SCROLLING LED DISPLAY WITH PASSWORD AND VOICE ABSTRACT The project mainly focuses on transmission of textual data through air interface by the use of GSM through asynchronous serial communication. The data will be processed by the microcontroller it programmed by embedded c language by using KEIL C compiler. The data will be displayed on led display on LED only after entering unique pass key. Existing System: How a reliable and an authentic wireless communication could be easily developed between a mobile phone and microcontroller using GSM (Global System for Mobile Communication) MODEM (Modulator-Demodulator). This technical paper explains GSM based e-notice board which can be widely used for multitude of applications including educational sector, traffic control, banks, and public advertisements, stoke exchanges etc. Proposed System: In this project we not only send the data, but send the data with pass code also. Which enables us to preve...

A SHOULDER SURFING RESISTANT GRAPHICAL AUTHENTICATION SYSTEM

A SHOULDER SURFING RESISTANT GRAPHICAL AUTHENTICATION SYSTEM ABSTRACT Authentication based on passwords is used largely in applications for computer security and privacy. However, human actions such as choosing bad passwords and inputting passwords in an insecure way are regarded as”the weakest link” in the authentication chain. Rather than arbitrary alphanumeric strings, users tend to choose passwords either short or meaningful for easy memorization. With web applications and mobile apps piling up, people can access these applications anytime and anywhere with various devices. This evolution brings great convenience but also increases the probability of exposing passwords to shoulder surfing attacks. Attackers can observe directly or use external recording devices to collect users’ credentials. To overcome this problem, we proposed a novel authentication system PassMatrix, based on graphical passwords to resist shoulder surfing attacks. With a one-time valid login indicator and ...
