Design and implementation of wireless IoT device for women’s safety

Abstract

As daily newspapers and telecast media gets flooded with rape and murder of young children and women, it becomes a national duty to safeguard their safety at all times. According to a statistic, more than a thousand children and women were raped from between January and October 2020 in Bangladesh. More than 2,700 cases of violence against women and children have been reported, including rape. According to the World Health Organization (WHO), one in three women is a lifelong victim of sexual violence. With the number of atrocities increasing every year, the need to alert someone for help using an advanced system becomes a necessity. A lot of these cases are not considered a serious issue in our country. In this precarious scenario, we propose a device that consists of ESP8266 microcontroller, pulse-oximeter and heart-rate sensor, gps, push button, reset button and a ESP32 wireless camera. The device is connected to the Blynk web server, where it continously updates the user’s pulse-rate and oxygen values. The device is very compact, and can be turned on by pressing the emergency button. It also turns on automatically when the heartbeat and oxygen values rise above the threshold value in case of an emergency. Once the device is turned on, it will send danger alert messages to the necessary contacts and the police station alarming that the girl is in danger. The text message also contains the exact location of the girl using a GPS. In addition, this device is also fitted with a ESP32 wireless camera which snaps a picture of the attacker. To conclude, this device is built based on real life scenario and has the adequate features to guide the women to safety.
