Hardware Control via SMS

System Overview
The system consists of two mobile connected by the existing cellular mobile network. One of the mobile is connected to the computer by USB data cable. The computer contains the series of computer program that is capable of retrieving SMS, processing and directing hardware to produce the desired output. The hardware part is connected to the computer by the parallel port.

2.2 Hardware Description:
2.2.1 Mobiles
The basic component of our project starts with two mobiles. These mobiles are used to send and receive SMS through the available cellular network configurations. One of the mobile is connected to the computer through usb data cable. The other is used by the user to send the SMS to the connected mobile. Since the project’s backbone is the SMS, the SMS has to be fed to the computer and this is done by mobile software which will be discussed under software discription portion.

2.2.2 USB data cable
The USB data cable is the connector that connects different hardwares to the computer. In our project, we have used this cable to connect the mobile to the comptuer.

Design and Construction of Noise Detector in Library

Library is the place of peace and silence where students get opportunity to study and view different reference materials. Peace and silence is the most important feature of library. But many times students dont give much attention to it and consider it to be the normal place. So students make noise in library and ruin its attribute. So taking this issue into consideration, we decided to fabricate a simple electronic device that can solve this problem.This project is for the design and construction of the NOISE DETECTOR IN LIBRARY. This device is able to detect the noise, compare the intensity of louder sound and hence producing the warning signal to the librarian. This system is very economical and helpful in maintaining peace in library.

In this project we have designed a technology to detect the noise and produce the output according to the intensity of noise made. When the sound exceeds the threshold, it is considered as noise which in turn triggers the timer and an output is seen in the LED. Sources of our literature survey are mainly the books, websites and consultation with the faculty members and interaction with colleagues. All those sources were very much useful for us to get knowledge about different components and upgrading our project.
