Abstract
As far as women safety is concerned. Especially in our country the standards are going on decreasing day by day. According to National Crime Records Bureau (NCRB) the incidents of kidnapping and abductions rose to 64 per million to 74 per million which is devastating. If it goes on increasing like this, In the coming years there will be a tremendous rise in crime rate especially against women. It is our responsibility to protect our mothers, sisters, friends and each and every woman in our family. There are many devices in the market for this application that is sending locations and alert messages to the family of the user. But, all the devices need the response from the user when they are in danger to send the alert messages or such to their family or emergency services. But there might be situations where the user has zero chances to respond or send any alert messages to their family. We came up with a solution where the alert messages and current location of the user are sent automatically to their family when they are in danger without any response from the user. We achieved it using the pulse rate sensor PPG (Photoplethysmography sensor) using which we measured the abnormal rise in heart rate when the user is in danger. This paper deals with the functionality and implementation of our idea in Embedded Systems and IoT.
Highlights
Safety standards especially for the women are getting worse day by day
Which restricts the users from interacting with safety device present with them? Users cannot completely rely on such devices which require the user’s interaction.There is a requirement of a device which works effectively and sends the alert messages even without any user’s interaction
After a long research we came up with an idea to design a safety device using PPGS (Photoplethysmography sensors) which is used for pulse rate monitoring in different medical devices, fitness trackers, blood oxygen level monitors
Summary
Safety standards especially for the women are getting worse day by day. A wide variety of safety devices in different forms with different functionalities are available in the market. Measuring the heart rate of the person using PPGS if it is high for more than ample amount of time and there isn’t any interaction from the user we will send the alert message along with the location to the family members and emergency services.For the time being we have designed the device for the women below 30 years without any health complications. We are trying to develop this in the form of a wearable which can be worn on hand and which even can’t be identified as a tracking or safety device
