          The coin-based mobile battery charger developed in this paper is providing a unique service to the rural public where grid power is not available for partial/full daytime and a source of revenue for site providers. The coin-based mobile battery charger can be quickly and easily installed outside any business premises.

The mobile phone market is a vast industry, and has spread into rural areas as a essential means of communication. While the urban population use more sophisticated mobiles with good power batteries lasting for several days, the rural population buy the pre owned mobile phones that require charging frequently.

Many times battery becomes flat in the middle of conversation particularly at inconvenient times when access to a standard charger isn't possible. The coin-based mobile battery chargers are designed to solve this problem. The user has to plug the mobile phone into one of the adapters and insert a coin; the phone will then be given a micro-pulse for charging. It does not bring a mobile from 'dead' to fully charged state.

The charging capacity of the mobile is designed with the help of pre defined values. It is, of course, possible to continue charging the mobile by inserting more coins. This compact and lightweight product is designed to cater for the growing number of rural mobile users worldwide. A suitable microcontroller is programmed for all the controlling applications. The source for charging is obtained from direct power grid and solar energy in case of non availability of grid power.

ACCIDENT DETECTION FOR RELEASE AIRBAG USING GSM, GPS&MEMS USING ARDUINO CONTROLLER

ABSTRACT:

     Main concentration of this project is to find out the vehicle which is met with an accident by using MEMS sensor and GPS, GSM to release Air bag.

              Vehicle tracking system is one of the hot topics in embedded systems industry. By using this project a vehicle can be tracked anywhere on the globe.  In this project arduino controller communicates with LCD, GPS module and GSM modem. This system will be placed in a moving vehicle. The arduino controller will poll GPS module in prefixed intervals and sends the vehicle location information (Latitude & Longitude) to central station over GSM network.

            When ever any accident occurs MEMS sensor detects the vibration of the vehicle and sends mechanical force, to ARM, by using GPS, we will get particular location where accident occurs, and then GSM sends message to authorized members & 108.

            One more best feature is when ever any authorized people gives message to GSM at accident location then it sends back the message of the accident location long and lat values.           

            This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/18V step down transformer

ADVANTAGES:

Ø  It reduces the death percentages in accidents

Ø  It gives immediate information to the belonging one

Ø  Simple and reliable

Ø  Low cost

Ø  Easily applicable

APPLICATIONS:

Ø  It is used for vehicle tracking

Ø   Whenever any authorized people gives message to GSM at accident location then it sends back the message of the accident location long and lat values.

FOREFINGER DIRECTION BASED ROBOT CONTROL

            This Robot will follow the direction in which we show our Forefinger. We place a sensor which can able to detect the direction of Forefinger and the output is transmitted via RF transmitter. In the receiver section RF receiver which receives corresponding signal will ask arduino microcontroller to move robot in that particular direction. Here we have four directions i.e. Right, Left, Forward and Backward. Robot is two wheeled and has a scrolled arrangement for front wheel operation.

This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/18V step down transformer.

A COAT WITH HEART ATTACK DETECTOR

Abstract:

                The primary function of this system is to monitor Heart Beat of the Patient and the Data collected by the sensors are sent to the   Microcontroller. The   micro controller transmits the data over the air. Here we are using the GSM modem in order to transmit the information.

               From the transmitter the recordings are sent as an SMS to the care taker or the expert which have been given as the recipient. Not only we send the information through GSM module as SMS we also display the readings on LCD. And when the conditions go abnormal then we sense those values and then alarm the people around by blowing the alarm and also sending by sending as urgency SMS.

                  The functioning of Heart Beat device is based on the truth that the blood circulates for every heartbeat that can be sensed by using a circuit formed by the combination of a LDR and LED. Depending upon the rate of circulation of blood the heart beat rate per minute is calculated. This calculated value is communicated to remote person through a GSM modem interface to it.

          Here we tacking the input parameter as a heart beat   this is sensed by the sensor circuit and then heart beat calculate by the real time clock. If the heart beat is greater than the predefined level the information send to the concerned person.
