3.     DHT11 temperature sensor
4. Buzzer
5. LED


Arduino
 Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

GPS module:
 A GPS navigation device, GPS receiver, or simply GPS is a device that is capable of receiving information from GPS satellites and then to calculate the device's geographical position. Using suitable software, the device may display the position on a map, and it may offer directions. The Global Positioning System (GPS) is a global navigation satellite system (GNSS) made up of a network of a minimum of 24, but currently 30, satellites placed into orbit by the U.S. Department of Defense

Dht11 temperature sensor:
DHT11 is a Humidity and Temperature Sensor, which generates calibrated digital output. DHT11 can be interface with any microcontroller like Arduino, Raspberry Pi, etc. and get instantaneous results. DHT11 is a low cost humidity and temperature sensor which provides high reliability and long term stability.

Led:   
A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength. The output from an LED can range from red (at a wavelength of approximately 700 nanometers) to blue-violet (about 400 nanometers). Some LEDs emit infrared (IR) energy (830 nanometers or longer); such a device is known as an infrared-emitting diode(IRED).

Buzzer:
Buzzer. A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses ofbuzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.

week 2 day 1

problem statement :
          
                                  At any emergency situation people get paniked and in that suitation, they may not be able to operate their smartphone applications, and cannot immediately defend the attacker and protect their childrens . The proposed system ca be useful for children for security purpose.It consists of a warable saftey device having sensors and an emergency button which when activated sends a alert message with location information to the victim's family and nearby police station.

week 1 day 1

Github : Github is a code hosting platform for version control and collabration ,it lets you and others work together an projecs from anywhwere

    we discussed the concept of asmart device for children above 8 age. we did a research analysis on the software requriments such as,
  operating system    : windows xp/7
  coding language     : java(jdk 1.7)
   web technology     :  servlet,jsp
   Database                :  my_Sql 5.0
   UGI for Database  :  sqlyog

week1 day 2

Background these project focus on the key aspect that lost child can be helped by the people around the child and can play a significant role in the child's safety until reunited with parents
