The main aim of the prototype development is to reduce electricity wastage. IR sensor module was used for receiving singnals regarding entry and exit of persons and automatically enable the controller to take any further action such as to switch ON and OFF the home appliances such as light, air-conditioner etc. The system is integrated with microcontroller, home automation and IR sensor interface using BASIC language. BASSCOM software was utilized to accomplish the integration. The system is activated when user enters the room and IR sensor sends signal to controller at home. Upon receiving the Sensor command, the microcontro ller unit then au tomatically controls the electrical home appliances by switching ON or OFF the device according to the user order. to the received message. The prototype has been successfully developed and it could provide an effective mechanism in utilizing the energy source efficiently. The System is basically designed for students in order to make them awake and also if they are slept, than to save energy by automatically closing fans and lights This paper mainly focuses on the controlling of home appliances automattically and providing security when the user is slept or not in the room. This system provides ideal solution to the problems faced by home owners in daily life. The system uses automatic controlling thus providing ubiquitous access to the system for security and automated appliance control.

INTRODUCTION CHAPTER I INTRODUCTION The development of digital information has led the rapid change in human lifestyle. The use of electricity is very important as one of the main source of energy that is vital in today modern life. Some kinds of mechanism using available technology could be used to reduce wastage in electricity usage. Thus a prototype based on a microcontroller device using SMS is developed. It can automatically control any electrical equipment at home remotely using sensing of person. Hence the electrical energy saving in daily life can be made more efficient and effective. As the technology grows automatic controlling has been widely accepted as a part of operation. The purpose of using automatic control is to provide widest coverage at minimal cost. Therefore the use of prototype would facilitate in controlling the electrical device at home from without switching on and off of device and low in maintenance and independent from any physical geographical boundary. At the present time, people use electrical energy as one of the main source of power of energy to operate any electrical device or appliance. Most of the people turn on the light and forget to switch off and may go for so many days to out of station. Leaving the light turned on continuously, lead to energy Waste . Thus this project is proposed to develop a system is to facilitate the home owner to optimize usage of electricity automattically. Light turned on continuously and it leads to energy waste. Thus this research is carried out to provide a mechanism through the development of a prototype to provide a service to the home owner to optimize the usage of electricity through remote control using automatic sensor controlled services. The motivation is to facilitate the users to automate their homes having ubiquitous access. The system provides availability due to development of a low cost system. The home appliances control system with an affordable cost was thought to be built that should be mobile providing remote access to the appliances and allowing home security. The followings are the objectives of the research project to ensure it meets the aim. To design a lamp and extension control system for smart home application using automatic systems. To design a circuit that can automatically switch ON and OFF the home appliance using Automation Board, To write a program that can send the IR sensor signal using assembly language in BASSCOM software. Chapter 2 gives a brief about the projects based on IR sensor which have been done in past and what they comprised of. This chapter also gives a detailed description of the components used in the projects, their description along with a clear understanding of the programming commands that have been used. Chapter 3 highlights the flowcharts and diagram related to the projects working and also a view of the systems working. Chapter 4 discusses the results & analysis of the project prototype Chapter 5 gives you the main conclusion which also includes the drawbacks involved in the system that can be rectified. REVIEW OF LITERATURE CHAPTER 2 REVIEW OF LITERATURE This section provides a previous study of related work regarding the application of AUTOMATIC control of devices in a various fields.

  • Medidor Online De Temperatura Y Humedad De Bajo Consumo
    Medidor online de temperatura y humedad de bajo consumo Estudiante: Jesús Santiago Fernández Prieto “Ingeniería Técnica de Informática de Sistemas” Consultor: Jordi Bécares Ferrés 11 de Junio de 2013 When I read commentary about suggestions for where C should go, I often think back and give thanks that it wasn't developed under the advice of a worldwide crowd. (D. Ritchie) A mi familia, novia y amigos. 2 Resumen Para este proyecto se ha diseñado un dispositivo con capacidad de conexión a Internet a través de un punto de acceso WIFI para el envío de datos y alertar en caso de posibles temperaturas y humedades críticas, definidas con un valor mínimo y un máximo. El diseño de este dispositivo se ha hecho teniendo en cuenta el reducir el consumo de energía para maximizar autonomía. El dispositivo está basado en una mota LPC1769 que posee un procesador Cortex-M3 de ARM el cual ejecuta nuestro programa desarrollado. Este programa hace uso del sistema operativo FreeRTOS (Free Real Time Operating System) que facilitará y nos asegurará estabilidad. La mota llevará conectada un chip WiFly que se usará para poder conectarnos por WiFi al punto de acceso. Cuenta además con un sensor SHT15 que permite, a la mota, tomar las mediciones de temperatura y humedad relativa. Estos serán posteriormente enviados al servidor. En caso de que en alguno de esos valores esté fuera del rango de seguridad se avisará al usuario a través de dos leds conectados también a la mota. Se le puede configurar una dirección de correo electrónico donde se enviarán alertas para enviar un correo al usuario advirtiéndole de un posible problema.

  • Microcontroller 1 Microcontroller
    Microcontroller 1 Microcontroller A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, The die from an Intel 8742, an 8-bit microcontroller that includes a CPU running at 12 MHz, 128 bytes of RAM, 2048 office machines, appliances, power tools, toys and other bytes of EPROM, and I/O in the same chip. embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. Some microcontrollers may use four-bit words and operate at clock rate frequencies as low as 4 kHz, for low power consumption (single-digit milliwatts or microwatts). They will generally have the ability to retain functionality while waiting for an event such as a button press or other interrupt; power consumption while sleeping (CPU clock 2 ATmegaxx micro controllers and most peripherals off) may be just nanowatts, making many of them well suited for long lasting battery applications.
