Design and implementation of wearable protective device for women with IoT

Women are facing numerous problems in their daily life. Presently there are a lot of solutions to this problem. But they aren’t that much efficient because they need a lot of manual operations to activate the device. To overcome this problem, the proposed methodology explores the IoT concepts such as measuring the vibration, heartbeat rates/pulse rates, temperature, and acceleration by sensors in the victim’s body. If any abnormality is sensed it sends an emergency message to relatives through an app notification. There are lots of gadgets available for women’s safety, but the lady cannot stay on the gadget at all the time. Instead, she could be monitored by wearing a smartwatch which comprises a vibration sensor (SW420), SPO2 sensor (MAX30100), temperature sensor (LM35), and an accelerometer (ADXL345). When any of the sensors detect signals more than the threshold range GPS is triggered to track the location coordinates and is sent to google Firebase from there it reaches our app as a notification. As soon as the well-wisher receives the emergency message, they can intimate the victim by pressing a button in-app so that the victim came to know that her emergency was noted and this makes her feel a little better which is the main advantage in this prototype. It is accessed by wireless technologies like GPS, Wi-Fi and monitored by nearby devices. This application helps women to come out of their circle and do whatever things they like without worrying about their security.
