4. Results - sakshichougule/Women-Safety-device GitHub Wiki

This chapter focuses on analyzing the results of the hardware-implemented and the discussion on optimization

4.1 Result Analysis

The prototype of the proposed safety device is realized using Arduino Uno Microcontroller and simulation is shown in Figure 5.1

Figure 5.1: Simulation on Proteus Software.

The purpose of the device is to protect the women caught in a dangerous situation. Once the emergency button is pressed or sensors readings exceed the threshold value, the Arduino Uno Microcontroller gets the required commands, and based on those inputs GPS module is activated which will start calculating the current latitude and longitude values of the victim. These calculated values are sent to the registered mobile number with caution: Danger Detected! HELP! message as shown in Figure 5.2. Along with this, a phone call is also sent to the concerned person via the GSM Module.

The latitude and longitude values are sent to the registered mobile number, along with this a google map link is also sent with the SMS which when opened using google maps gives the exact location of the victim as shown in Figure 5.3. So tracing the location on the map family member can reach to help the woman in need. This is how the device works and assists in generating a quick help to protect the victim.

The Final Hardware Implementation of the Project is shown in Figure 5.4

5.2 Discussion on optimization

The main parameters we have considered to optimize the working of the device include: to utilize the minimum number of components, low power consumption, and lesser memory requirement. The hardware components used are - Arduino Uno Microcontroller board for providing efficient power requirement, Skg13bl(GPS) and Sim900A (GSM) module which low power consumption of 45mA, and 1.5mA respectively with faster execution time. Our project uses the minimum number of components yet these components integrated together are effective in protecting the women.
