WomenSaf et yRel at edFac t o r sThere are several techniques that used in women safety device,• Location Tracking.• Notification.• Sensors.• Image capturingA. Location TrackingGSM stands f o r Global System f o r Mobi l e Communication. It is a digital mobile cellular network which has been used for transmitting the voice and data SIM 800C is a complete Quad-band GSM solution. It operates in low power consumption w i t h a voltage range o f 3.4v~4.4v.It gives an efficient transmission when compared to other types. GPS is a technique which is used to f i n d out the actual posi ti on o f the person. I t communicates directly to the satellite by using the GNSS network.
B. NotificationWith the help of GPS and GSM the location is identified. And thus the identified location is shared to the people through SMS, Email ID, calls Etc. With the help of buzzer an alarm sound is generated, through this sound the people who are in minimum distance can help them.C. Image CapturingThe video camera is used to capture the image or video i n order to send the photos or videos to the registered contact fo r the later Investigation.D. SensorsSensor is a device which calculates or discovers a physical property that indicates, or otherwise i t responds to the specific devices. There are several types o f sensors whi ch are used to measure several conditions; some o f the sensors are detected by using various physiological sensors namely: M E M Sensor, Fl ex Sensor, Pulse Rate sensor, Temperature Sensor:a. MEMS SensorMEMS Stands f o r Mi cro-El ectro-Mechani cal – Systems. This sensor is used to measure the acceleration. I t can be applied to any sensor by using microelectronic fabrication technique. Since the range o f an accelerometer varies i n sensitivity i t is used in shock and blast applications.b. Flex SensorFl ex sensors is a variable resistor. The resistance o f the sensor increases when there is a movement occurs in a component due to high pressure. This sensor has two output wires and thus the resistance between these two wires varies accordingly to the pressure applied. It can be used in toys, horn switch, gaming, glove, auto control. It can also be used in music and computer interfaces.c. Pulse Rate SensorThe output o f the pulse rate sensor is in the form of digital. That digital output can be combined with the Microcontroller in order to calculate the Beats per Minute (BPM) rate. The led flashes fo r every heartbeat, when heart beat detector is working.d. Temperature SensorTemperature Sensors calculate the amount o f heat energy or even coldness which is generated by an obj ect o r system, f o r t o “ sense” o r detect anyphysical change to the temperature producing an analog or digital output.
The occurrence o f threats to women leads to increase in number o f security devices and applications. This research shows the various factors which have been used in applications and smart devices developed fo r women safety. I n this paper, the various techniques used so far for the sake o f women safety against the fraudulent people have been discussed. Also a brief explanation about the devices and components used in these techniques are also provided. Click Here
