ProTecht – Implementation of an IoT based 3 –Way Women Safety Device

In this paper, an IoT based women safety device is proposed and implemented for effective self-alert and protection. The proposed device is a three-way safety module for it provides self-defense, evidence recording and tracking information. Due to increase in the rate of crimes against women, today's age safety of women is a major concern. For self-defence the device produces shock to the attacker through a nerve stimulator and rings a buzzer on pressing a button. It also allows to record evidence via a video camera which gets activated through the button and stores the footage in the Raspberry Pi. The prototype also consists of a GSM and GPS module which is activated by voice command through an Android Application. When the user will say the words "emergency" in his mobile application the device will send SMS alert containing the location of the user and auto dial the pre-set emergency contact number. A microphone and speaker are connected with the GSM module through which the user can hear and speak with the contacted person. Hardware used are Raspberry Pi 3 b+, GSM module, GPS module, relay module, buzzer and nerve stimulator.
