ABSTRACT Underground cables area unit at risk of a good style of faults thanks to underground conditions, wear and tear, rodents, etc. additionally police investigation fault supply is tough and also the entire line is to be mammary gland so as to see the whole line and fix faults. Therefore here we tend to propose cable fault detection over IOT that detects the precise fault position over IoT that creates repairing work terribly straightforward. The repairmen understand specifically that half encompasses a fault and solely that space is to be mammary gland to observe the faulty supply. This protects heaps of your time, cash and energy and additionally, permits America to service underground cables quicker. We tend to use IOT technology that permits the authorities to observe and check faults over the web. The system detects a fault with the assistance of a possible divider network set across the cable. Whenever a fault gets created to some extent shorting 2 lines along, a selected voltage gets generated as per the resistors network combination. This voltage is detected by the microcontroller and is updated to the user. The data sent to the user is that the distance to that voltage corresponds to. The microcontroller retrieves the line information and shows over the alphanumeric display, additionally, it transfers this information over the web to show online. We tend to use IOT Gecko to develop the online the web the net system that links with the system to show the cable faults online.

SYNOPSIS : Simultaneous dimming controlling and data transmission are usually required in a white LED based indoor visible light communication system. However, the dimingcontrolling of LED normally interferes the data transmission due to the modulation nonlinearity of LED. In order to solve this problem, a scheme by separating the LEDsfor the functions of dimming control and data transmission respectively is proposedin this paper. In the scheme, the LEDs used for dimming control function are driven by a dc amplified circuit, and the LEDs for data transmission are driven by a digital modulation circuit respectively. In this way,the modulation distortion to the data signalcaused by the modulation nonlinearity canbe avoided even if the dimming is at highlevel dc driven current. The proof-of-conceptexperiment of a 2.5Mbit/s visible lightcommunication system demonstrates that thedimming controlling and data transmission canbe realized simultaneously in a simple way,and the data transmission is not affected by the dimming controlling function. Comparedto previous methods, the scheme in this paperis simpler and cost effective, and makes sensewhen high rate data is transmitted in a visible light communication system.

ABSTRACT Nowadays most of the vehicle in a critical situation many vehicles faces accident, due to this lot of person lost their lives. Some people can be saved at that time, but because of a lack of information, time and place it may not be possible. Our project will provide an optimum solution to that drawback. The accelerometer sensor is used in a car alarm application Dangerous driving can be detected with an accelerometer sensor. This project used to collect crash recorder of the vehicle movements before, during and after a crash., an accident can be recognized from the accelerometer sensor. when an accident happened means immediately the vehicle number and person contact number will be transferred to the police control room or a rescue team. The police can immediately track the accident location from where the message came. Then after confirming the location, necessary action will be taken. In a second application on an uncertain situation, many of vehicle that has a central locking system, Such as door locking system faces many problems due to the automatic locking system. If no way to open the lock. This project will provide a solution to this situation. This can be done by using GSM Technology.

ABSTRACT : These days, even though there are many new IT services, these cause another types of problems. There are increases in the diversity of services and service quality, but there is also much higher energy consumption. Furthermore, recent environment friendly technologies have some problems with efficiency, and it is still premature to achieve any greatly positive effect. At this point in time, renewable energy coincides with sustainable growth. There are many studies and commercial products involving photovoltaic and wind power, and these have significant roles in propagating environment-friendly technologies. In case of electric cars, meaningful, decreases in energy consumption cannot be achieved since fossil fuel is simply converted into electricity. Meaningful change means that each car no longer consumes fossil fuel and every thermoelectric power plant has to make more electricity to afford cars’ energy needs. Moreover, a huge infrastructure of electricity stations on every street is needed, and it is difficult to catch up with the fuel efficiency of fossil cars immediately. Due to these technical troubles, the importance of renewable energy is getting bigger. In addition, the power market would become more important, and it is expected that the influence of renewable energy as sustainable growth will be much larger with the Smart Grid. However, it is not easy to be connected to commercial electricity in these kind of generating systems, because each type of renewable energy such as solar and wind power, is slightly different and needs to be managed. Furthermore, renewable energy can provide almost indefinite power but it is hardly expected to be stable

The main aim of this project is that it saves energy by putting on the lights of the system only when the system detects movement of vehicle. The system switches on the street light ahead of the vehicle and switches off the trailing lights simultaneously. In order to detect movement of vehicles, sensors are used. The system automatically puts on the lights that are ahead of the vehicle detected and as soon as the vehicle moves ahead, the trailing lights are switched off. This is better than the existing system where the street lights are kept on always unlike this system where the street lights are put on only when movement of vehicle is detected which helps in saving lot of energy. During day time these lights are dim as this system has the capability to sense external lights. Thus this system senses the external light and then accordingly puts ON or OFF the street lights. It uses PWM to control the intensity through microcontroller. The sensors sense the vehicle movements and send it to a microcontroller that initiates commands for switching the lights ON/OFF.

ABSTRACT: Gas leakage tragedies and accidents have led to heavy losses over the years. So it is very important to detect any gas leakage and prevent any accidents. So here we propose a system to detect LPG/CNG gas leakage scenarios and provide a security alert to intended users. We propose to build the system using a MQ6 gas detection sensor and interface it with Atmega 328 microcontroller along with an LCD Display. Our system uses the gas sensor to detect any gas leakages. The gas sensor sends out a signal to microcontroller as soon as it encounters a gas leakage. The microcontroller processes this signal and a message is displayed on the LCD so as to alert the user.

Abstract: The proposed project is a wireless communication system that keeps a track of remote patient’s body temperature and displays it to doctor by using RF communication. Usually a doctor or an attendant has to regularly keep a check for the patient’s temperature thus, this task becomes tedious after sometime. Hence, the system is used to read remote patients temperature using a digital temperature sensor and sends it to microcontroller. The microcontroller encodes the readings thus received, displays it on LCD and sends it to receiver by RF over the air using an RF module. The receiver decodes the data and sends it to another microcontroller that displays it on LCD screen. Hence, the doctor can continuously keep a check on the patients reading displayed on the LCD through receiver wirelessly.

ABSTRACT: Authentication has always been a major challenge in all types of examination. Verification of the authentic candidate is not an easy task, and also it consumes a lot of time and process. Here we propose a fingerprint based examination hall authentication system. The system is designed to pass only users verified by their fingerprint scan and block non verified users. Our system consists of a fingerprint scanner connected to a microcontroller circuit. The person needs to first scan his finger on the scanner. The microcontroller now checks the persons fingerprint validity. If the fingerprint is authorized the microcontroller now sends a signal to a motor driver. The motor driver now operates a motor to open a gate. This ensures only authorized users are allowed to enter the examination section and unauthorized users are not allowed to enter.

The project is a home automation system that uses DTMF connection to control the home appliances remotely. It overcomes the limitations of conventional wall switches that have to be operated by physically going near to then and switch on the button. The system uses DTMF by which one can control home appliances by dialling the designated number for particular load. One can operate it from home phone or by making a call to home number from outside. The system uses DTMF technology that receives commands from phone and produces digital output which initiates relay driver to switch ON/OFF the load appliances. For this the system we use De-Multiplexer, flip flop IC, DTMF Decoder. This DTMF technology allows the user to send commands to operate the appliances via a mobile phone and avoids the use of microcontroller. In order to use this system the user has to make a call to the mobile phone connected to this system. Once the call is received by the mobile phone connected to the system, the user can now send commands to operate the home appliances. For this the system makes use of lamps to demonstrate AC loads and uses 12V transformer to power the system.
