Review on Sensor Based Smart Alert System

The Internet of things (IoT) has turned the way of implementation of most of the systems completely. Modern security systems with the implementation of cloud connectivity to the security devices .We analysed through the statistics data and we came across a significant percentage of people who go through harassment or other kind of abuse throughout the time respectively. In this digital era where all the basic works are done smoothly we believe that a security of the person should also be carried and implemented in with ease and smartness. As of today we face the problem of late in action towards these types of complaints in the system or we can say that there is a time bound for these kind of situations which is a critical situation for a person going through it, so to make it a quick fix. Based on the survey done on the existing system we propose to have a device which is the integration of multiple devices hardware comprises of a wearable or carrying smart system that endlessly communicates with sensible phone that has access to the web. This makes easy to track and communicate with the victim.

Cinch and Sterling Analog Circuits for Laboratory

As we know that there is ever increasing demand for compact circuits and less complex wirings over the board, a technological boon evolved for such demand is Printed Circuit Board (PCB). A PCB will mechanically supports and electrically connects electronic components using conductive tracks, pads. These boards will have minimal chances for short circuits, components on the board are fixed; another advantage is creation of multiple boards using single design. Taking this technology forward to our everyday life, we implemented analog communication laboratory circuit, Schmitt trigger.
