DC MOTOR CONTROL USING GSM (P.W.M TECHNIQUE)

DC MOTOR CONTROL USING MOBILE ABSTRACT

Now a day's every system is automated in order to face new challenges in the present day situation. Automated systems have less manual operations, so that the flexibility, reliabilities are high and accurate. Hence every field prefers automated control systems. Especially in the field of electronics automated systems are doing better performance.

                      This project mainly deals with the speed control of a DC Motor using a MOBILE. The type of speed control that has been chosen here is pulse width modulation PWM. This project deals with development of DC MOTOR control using MOBILE, where a message is send to the GSM interfaced to the MCU. 12V DC Motor drives widely use  Micro controllers and  The project detail design and complete hardware based high performance DC drive control system  will be  implemented. Most recently new requirements have arisen. These include faster torque control update with flexible design capability of motion peripherals for high performance military drive applications. Pulse width modulation type of speed control is chosen here because of high accuracy, high reliability, quick response and high efficiency.

Our project deals with the types of problems that we face due to disturbances in supply voltage or load on the motor and enables us to overcome these difficulties by helping us with the appropriate software and hardware.

     We propose to design an embedded controller that helps us maintain the speed of the DC machine within the specific limits and a remote operate the embedded controller. Here, the pulses from the remote are sensed by sensor and are transmitted to the embedded controller. This controller contains a programmable PWM port. The output of this PWM port is used to control power delivered by a power regulating   device

AUTOMATIC HOME SECURITY SYSTEM USING WIRELESS TECHNOLOGIES GSM AND ZIGBEE

AUTOMATIC HOME MONITORING SYSTEM

AIM:

           The main aim of this project is monitoring of smart home remotely and providing security when the user is away from the home.

PURPOSE:

              The Purpose of this project is to provide controlling of home appliances remotely and will also enable home security against instruction in the absence of home owner by using GSM and zigbee technologies.

Description:

                  This paper proposes to investigate a cost effective solution that will provide controlling of home appliances remotely and will also enable home security against instruction in the absence of home owner. The motivation is to facilitate the users to automate their homes having ubiquitous. This paper proposes a system that allows user to be control home appliances ubiquitously and also provide security on detection of intrusion via SMS using GSM.

          It provides flexible and comfortable services for the home owner both inside and outside the home. The services of the system consist of the ability of the owner to control and monitor the status of the home appliances and devices remotely. Such devices may be an air conditioner, a lighting system, an alarm system, a dishwasher, a refrigerator, entertainment devices medical devices, or electronics systems for special needs. Base on a query SMS, the result will be lookup from a database and returned to the sender via SMS. User can control and monitor the home electrical device from office by computer or by SMS on mobile phone. HARDWARE USED:

• Microcontroller
• Power supply
• GSM
• ZIGBEE Modules

SOFTWARE TOOLS:

• Keil u-Vision
• Embedded ‘C’
• Express PCB

ADVANTAGES:

• Low cost
• Security
• Time consuming
• Less manpower 

RESULT:

By using this project we can control our home appliances from outside of home and gives the security to them.
