GSM based Distribution Transformer Monitoring System  ABSTRACT: This project is about design and implementation of a mobile embedded system to monitor and record key parameters of a distribution transformer like load currents, oil level and ambient temperature. The idea of on-line monitoring system integrates a global service mobile (GSM) Modem, with a standalone single chip microcontroller and different sensors. It is installed at the distribution transformer site and the above parameters are recorded using the analog to digital converter (ADC) of the embedded system. The obtained parameters are processed and recorded in the system memory. If any abnormality or an emergency situation occurs the system sends SMS (short message service) messages to the mobile phones containing information about the abnormality according to some predefined instructions programmed in the microcontroller. This mobile system will help the transformers to operate smoothly and identify problems be

VSSoft   “OPTIMUM ENERGY MANAGEMENT SYSTEM” CHAPTER-I                                                  INTRODUCTION The project is designed to monitor the number of persons entering as well as exiting a room. Electrical loads are switched ON as the first person enters and switches OFF when the last person leaves. IR sensors used in combination with microcontroller to monitor all the operation. This helps in saving lot of energy.There are two pair sensors, each kept at certain distance from the other. One pair of sensor consists of transmitter and a receiver, kept exactly opposite to each other. The transmitting part emits modulated IR light which is received at the receiver end and fed to a microcontroller of 8051 family.When a person enters the room then microcontroller senses it (with the help of IR sensors) and increment the count and displays it on 7 Segment display and also switches ON the load. In the same way when a person exits the room, the lamp is OFF. Th
