Women are subjected to an increasing amount of harassment these days, which is troubling. The situation is extremely serious in both developing and developing countries. As a result, it poses a serious threat to women's empowerment as well as a country's fiscal development. We are developing IoT software and an Android app to make women's movement safer in this project. By pressing the device's emergency button, women will receive immediate and comprehensive safety assistance. In the event of an incident, this system will monitor the user's location in real-time and send it to a local police station and volunteer. This device will also provide the user with the location of the nearest safe zone. Furthermore, this interface can be used both online and offline. If the user does not have access to the internet, the computer can also be used to contact the nearest police station and volunteer assistance. Arduino uno, GPS, GSM, Bluetooth, and other components make up the system. The combination of both of these factors makes this product both inexpensive and simple to use.

This project is based on pick-and-place machines for placing surface mount devices onto the printed
circuit board. In general, the SMT pick and place robot using an end effectors to pick and place the
component on the PCB and a controller is used to control the movement of the stepper motor. Our SMT
pick and place machine is designed with a Cartesian configuration, and the Arduino UNO controller
with the CNC shield controls the stepper motors. The end effectors use a vacuum suction pen to pick and
place the components and a belt mechanism is used in the z-axis for up-down motion. Our machine is
portable and well suited for small scale industries. Our project satisfies one important sustainable
development goal - industry, innovation, and infrastructure.

Nowadays all types of garbage are dumped into the dustbin at the buildings (houses), hospitals etc., Hence it is difficult to segregate it. To avoid all such problems, we are going to implement a project where segregation of wet, dry, plastics and metallic wastes automatically using automated smart dust bin and afterwards signal is sent to the Mobile phones. The automated smart dust bin has several features and the main feature of it is to separate the waste automatically. The bin will have four compartments for the segregation of the wastes: for plastic waste, for wet waste, for dry waste and finally for the metallic wastes. Apart from this the bin will have motor for the rotation of the bin. This project makes it hands-free and evidently more hygienic method of separation. The bin will also notify about the amount of wastes filled through an LED. The bin will also alert by sending a message to phone to tell that it is time to throw the garbage. This idea will help us to dispose the waste in a hygienic manner. This project mainly concentrates on domestic wastes whose value is unrecognized since people do not spend time in separating the wastes. Instead of sending them to municipal corporation, waste can be sent directly for recycling if waste is separated at household level.
