Design and Implementation of Wireless IoT Device for Women’s Safety

Abstract—Nowadays, women face imminent risk of sexual harassment, rape and molestation in the streets as male predators roam around in search of their potential targets. In this precarious scenario, women needs to be protected in the street for their safety. To address these challenges, in this paper, we propose a wearable device that will protect and enhance the safety of women. This goal is achieved by analyzing the user’s pulse rate and oxygen measurements and updating them on the Blynk IoT web server. The user’s pulse-rate and blood oxygen saturation is determined by acquiring raw heart-rate and oxygen values from a pulse oximeter and oxygen sensor installed at the heart of the device. Real-time monitoring of user data is achieved by transferring sensor data to the Blynk IoT web server. This wireless device is specifically programmed to continuously monitor the user’s pulse-rate and oxygen values and react in case of a danger situation. It does so by detecting the abnormal pulse-rate and oxygen values, after which it sends the alert text message along with the location and live video streaming to the guardian’s mobile device via the Tasker app. Meanwhile, the alarm starts ringing. Besides, we validate our system architecture using different real time test cases. Moreover, we present a comparison of our proposed architecture with existing literature’s.
