Smartphones have completely altered the mobile communication scene. Wi-Fi, global positioning system navigation, high-resolution cameras, and touchscreens with high-speed internet access are just some of the cutting-edge capabilities that these devices offer, allowing users to stay in constant contact with the present. Since many of these features are embedded deeply in the mobile operating system, they are typically inaccessible to the average user. However, Google released Android, a revolutionary operating system. Because of its open system architecture, this platform encourages third-party development and a debugging environment that users may change to create their own unique apps. In this research project, we examine the development of an Emergency Based Remote Collateral Tracking System app on the Android mobile platform from Google. There are three main forms of emergencies: those involving the heart, those involving personal safety, and those involving the roads. Users who own and operate motor vehicles are the primary focus of this app. Our program can keep tabs on the driver’s pulse by connecting to a heart rate monitor. Our application has a backup function in case of anomalies. First, it sends SMS messages containing the user’s location data after using GPS to do so.

These days, safety measures can t be neglected. In a world where digital risks are becoming more prevalent, efficient security has become an essential aspect of any system or business. Protecting valuables now requires a defensive strategy with several layers. Security systems play an important role in today s modern, industrialised society. The security system is primarily intended to address the need for the protection of hard-earned treasures (jewels). Unlike the current method, which uses physical locks that are readily falsified, this system uses Bluetooth and RFID tags in conjunction with digital (electronic) code locks to unlock the door automatically once the series of authentications is validated and emits alarm noises when any discrepancy happens. The ability of subsequent layers of defense to prevent intrusion is unaffected by the failure of an earlier one to provide detection. In this effort, we use IoT to design and build a fully automated security system that will operate with no more human intervention when it is put into place. In addition, the system s overall cost of adoption is far lower than that of any other consumer security solution now on the market.

In today s world, security is a very important issue. People should always keep their belongings safe. To increase security, this research work proposes a IoT-based smart lockers with sensors and access keys with security, verification, and user-friendly tools. This model alerts the user when someone else tries to access their locker and quickly sends an alarm to the authorized user, and provides the option to either grant or reject access to the valid user. In this paper, smart locker is kept registered early to use a locker in the bank, office, home, etc. to ensure safety. The user demands to send an unlock direction with the help of microcontroller NUDE MCU ESP8266 and after accepting the command from the cloud (BLYNK APP), only the user can unlock the closet and access the valuables. This study has also introduced the encroachment detection in lockers with sensors and finally installed smart lockers with fire alarms for security and reliability.

Every person must take precautions in the current pandemic crisis, such as wearing protective gear, keeping a safe distance, cleaning their hands, and avoiding touching anything unless absolutely essential. However, there is a potential of disease transmission while touching objects like tables, doors, cars, and other things. Therefore, this study has proposed a proposal to stop them; the project is based on automation, in which an automatic door closing and opening mechanism has been created once the voice command is given. In this scenario, when a proper voice command is provided, the mechanism is activated to open and close the door automatically. Hence that there is no direct human contact with the door, which will assist stop or slow the spread of pandemic disease. The developed Arduino-based module can automatically close and open the door. These devices produced a regulator for the input, which uses the Android s Bluetooth signal. Arduino-based Android customers may easily open and close the door with their phones by communicating via Bluetooth technology. Within range, Bluetooth Classic (BT) makes it possible to connect an Android device. You may open a door with a personalized audio message and operate it by speaking into modules. Here, everyone is using various modules, such as voice commands, to control various modules. When a voice command is provided, the door will open and close on its own.
