Three Phase Inverter for BLDC Motor Drive Introduction Brushless DC Motor or the BLDC Motor is a rotating electric motor consisting of stator armature windings and rotor permanent magnets whereas in a conventional brushed DC motor the stator is made up of permanent magnets and rotor consists of armature windings. The conventional DC motor commutes itself with the use of a mechanical commutator whereas brushless DC motor needs electronic commutation for the direction control of current through the windings Industries using three phase devices like induction motors suffer a lot from the menace of power instability and have invested a lot in alternative means like the power generators which has many disadvantages like noise and other forms of pollution. The main objective of this three phase inverter project is to have Industries using three phase devices like induction motors suffer a lot from the menace of power instability and have invested a lot in alternative means lik...

SCADA   Based for Industrial Gas Monitoring and Controlling System Introduction In today’s world, automation industry is the highly growing field, because it provides great advantages over the manually controlled industrial applications. Industrial automation provides features such as security, data storage , data transfer and monitoring. This Industrial Gas Monitoring and Controlling system demonstrate  an application to make it useful in  industrial station automation system. In this project we have used multiple sensors to sense the various parameters and acquire data. Zigbee module is used to transfer data to remote monitoring location.    The remote monitoring station consists of a server PC to continuously receives data from the zigbee receiver module, then it displays those values in Graphical User Interface. It helps the user to easily understand the current status of industrial conditions and also in generating the periodic reports ...

Bank ATM Security System Introduction: User ATM security is the prime concern for every bank as it helps banks to achieve customer satisfaction and provides opportunities for them to grow their business. The user always looks for a bank which provides him the safe and secure banking solutions with minimum risk factor. This  Bank ATM Security System  provides security for the user ATM’s provided by the banks. For this, it takes the help of GSM Technology, each use will have a unique code for ATM transaction. User needs to enter the code while opening the ATM the security system and it generates a unique encrypted code for user access and sends SMS  to user with the help of GSM module attached, user needs to enter this code in order to open the account in an ATM within a specific time frame, otherwise the system locks the door and denies the access.  Block Diagram: Project Description: Micro-controller  This is the most important segment...

AGRO ELECTRONICS SYSTEM: Appropriate environmental conditions are necessary for optimum plant growth, improved Crop yields, and efficient use of water and other resources. Automating the data acquisition process of the soil conditions and various climatic parameters lead to plant growth to collect information at high frequency with less labour requirements.       In order to prevent dry running of motor and allow automatic restart of motor, sufficient water level is regained. Whenever water falls below LL level, micro-controller switches OFF the motor and sends SMS indicating dry running conditions. When the water rises beyond HL level, the micro-controller switches ON the motor again and sends sms indicating resumption of task. User need to go again and again and check the water level, he will get the alerts automatically whenever water is below the HL level.        In order to ensure maximum reliability, one temperature senso...

Wireless Automatic Meter Reading System for Power Measurement, Load Control and Billing:   Introduction Due to use of  improper power management systems, the power requirement is increasing in the development of country’s economy. Over the past years, metering devices have improved a lot, and are expected to become even more advanced, offering more and more services. Meters in the past were electro-mechanical devices with poor accuracy and lack of ability. Recent developments in this direction seem to provide opportunities in implementing energy efficient metering  technologies that are more precise and accurate, error free, etc. The implementation of Wireless Automatic Meter Reading System(WAMRS) provides with many vital features as compared with the analogue utility meter reading with man power. Working of WAMRS: WAMRS provides a two way communication between the electricity company and the load by sending in a lot of power parameters and control s...

Voice and GSM Alert Based Home Security System: Introduction: Home security in India has been a major issue, because day by day crime rate is increasing and everybody wants to take proper actions to prevent this crime rate. In addition, there was a need to take the advantage of the technological advancement to automate home so that a person getting off the office does not feel insecure. The project is aimed at developing the security of Home against Intruders , Gas Leak and Fire . If any of these cases happen while your are outside the home, this  Voice and GSM Alert Based Home Security sends SMS to the emergency number provided to it. User can also add unique voice based alert feature in order to provide voice alert to watchman or nearby houses. Block Diagram: Project Description:   In this project we interfaced 8051 microcontroller with Motorola’s C168 GSM mobile phone to decode the received message. The protocol used for the communication between th...

OTP AND BIO-METRIC TECHNOLOGY BASED LOCKER SYSTEM: INTRODUCTION OF PROJECT:        User home security is the prime concern for every user as it provides opportunities for them to work freely without worrying  about the home security. This OPT and Bio-metric Technology Based Locker System project provides a security system for the user’s house. For this, it takes the help of GSM Technology, each use will have a unique ID code for the user’s door. The security system will generate a unique encrypted code for user’s access and will SMS it to user with the help of GSM module, user needs to enter this code in order to open the door, otherwise the system denies the access and lock the door. Block Diagram: Description: Mobile Phone     In this project we have used one cell phone for user to send a unique code to his mobile. User’s  cell phone will use GSM Network for communication Microcontroller  Micro-c...

Introduction   The Android Mobile Phone Platform by Google becomes more and more popular among software developers, because of its powerful capabilities and open architecture, so we have created this Android Letter Box . As it is based on the java programming language, its ideal lecture content of specialised computer science courses. We think it is a great platform for a robotic system control, as it provides plenty of resources and already integrates a lot of sensors. The java language makes the system very attractive to apply state-of-the-art software engineering techniques, which is our main research topic. In this Android Letter Box Project we are using Android application, GSM  technology  and Micro-controller to solve the problem. As the time moves, the life style of the people has completely changed and there is no time for the people for micro management of every issue personally. So, this is the right time to provide some space to the technolo...
