CHAPTER 1 INTRODUCTION 1.1 Introduction of Project ―GSM based Control System‖ implements the emerging applications of the GSM technology. Using GSM networks‚ a control system has been proposed that will act as an embedded system which can monitor and contr ol appliances and other devices locally using built-in input and output peripherals. Remotely the system allows the user to effectively monitor and control the house/office appliances and equipment via the mobile phone set by sending commands

In the early power systems were mainly Neutral ungrounded due to the fact that the first ground fault did not require the tripping of the system. An unscheduled shutdown on the first ground fault was particularly undesirable for continuous process industries. These power systems required ground detection systems‚ but locating the fault often proved difficult. Although achieving the initial goal‚ the ungrounded system provided no control of transient over-voltages. A capacitive coupling exists between

Study of passive filter characterization for PCB application Chapter 1: Introduction Project Description Passive filters are relatively simple electronic part that consists with resistors‚ capacitors‚ and inductors. The function of the passive filter is to allow a certain range of frequencies to pass‚ can be used to separate signals‚ passing those of interest‚ and also can reject noise and attenuating the unwanted frequencies. In this project‚ there are three type of passive filters that

Humidity Sensors Humidity Humidity is defined as the water vapor content in air or other gases. Humidity is usually measured in terms of absolute humidity (the ratio of the mass of water vapor to the volume of air or gas)‚ dew point (the temperature and pressure at which a gas begins to condense into a liquid)‚ and relative humidity‚ or RH (the ratio of the moisture content of air compared to the saturated moisture level at the same temperature or pressure).
