Internet research has been done in order to know more on the relay.






Results:
Relay







Relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used.
Relays are used where it is necessary to control a circuit by a low power signal or where several circuits must be controlled by one signal.
Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on and off so relays have two switch positions.
The coil of a relay can passes a relatively large current, typically 30mA for a 12V relay, but it can be as much as 100mA for relays designed to operate from lower voltages.
Relays are usually SPDT or DPDT

WEEK 6

Title: Smoke Sensor / Detector(research further device)


Objective: To search the related information of the smoke sensor that will be used in this project.
Contents / Procedures: In order to understand more on the features of this sensor, the internet research has been done.


Results:
Smoke  detector is one of the common devices in a house security system.
As defined by the Wikipedia, smoke detector is a device that detects smoke, typically as an indicator of fire. Most smoke detectors work either by ionization detectors or by photoelectric detectors while others use both detection methods to increase sensitivity to smoke. Usually, in many single family detached and smaller multiple family housing, a smoke sensor is often powered only by a single disposed battery.
 Both ionization and photoelectric detectors are effective smoke sensors. Ionization detectors response more quickly to flaming fires with smaller combustion particles while photoelectric detectors respond more quickly to smoldering fires.
The smoke sensor detects smoke from a fire and sounds an alarm from the buzzer.
The smoke sensor that is under consideration to be used in this project is MQ2 Smoke Sensor. For this project, the smoke sensor will sense the smoke and buzzer will activated when there is an excessive amount of smoke.



This smoke sensor characteristics as below:
Wide detecting scope
Stable and long life
Fast response and high sensitivity
Sensing resistance: 3k ohm - 30k ohm
Suitable to detect smoke, LPG, alcohol and hydrogen
Detects combustible gases and smokes in a range of 300 - 10000ppm
The sensitivity of this sensor can be adjust using potentiometer
Conclusion: This smoke sensor is the device to detect the excessive amount of smoke. For this project, it will send the signal to the micro-controller and from the micro-controller, the signal will be send to the output device which is buzzer.

WEEK 3

CONSTRUCT A GSM  CIRCUIT

Introduction

The  objective of project GSM controller the house appliances is to provide a wide range and variety of customer with a controller GSM. Their main aimed at developing the safety of home against light, air conditioner agitated with Automatic Temperature Sensor and fan. In any of the above three cases any one met while you are out of your home than the device sends SMS to the system no provided to it.

The report consists of a background into the area of 8051 microcontroller and mobile communication, how they are interfaced to each other and AT (Attention) commands set used in communication.

However, it is unrealistic to expect the safety control the home appliances to plan the generation, transmission and control systems such on and off the electrical appliances are can be control. Some of these devices which are expensive but consist of reliable system and there are some cheaper devices which are productive too but still, all this devices has their own limitations. Even though technology plays a main role in developing good automated smart switching module but still there many addicts who are concern on the price tag(costing)of the devices itself [1]. Such outages and disturbances can be quite disastrous in the

case of sensitive loads, such as computers, which are now extensively used in modern commerce and industry.

            Looking into all this aspect in the real life habit, a stable and acceptable solution which is the SMS remote control Safety Home Module for remote access and control of electrical appliances via GSM modem has been designed. Safety home will be the future of homes. Equipped wit the latest technology, safety home has potential to become a reality in the new market with latest technology. Safety Home System is as shown below in Figure 1.1 and the hardware connection of the application on figure 1.2.The SMS controller as the primary control unit provide reliable structured approach and monitoring status compare to the conventional method(CM). In this system, the SMS is used for switching basic electrical appliances using conventional method and also remote switching via short SMS. This entire system enables the end user to interactively communicate with the SMS controller in any circumstances.

            The home appliances controlled by using the SMS switching are as appended below:-

1)      Light

2)      Air Conditioner agitated

3)      Fan

4)      Error Detection System

Literature Review

            Most of current can be control about home appliances can be control by GSM remote. The number of methods and approaches being used or proposed to estimate the GSM remote can be programmable control the home safety. Home safety will be the future of homes. Equipped with the latest technology, home safety has potential to become a reality in the home market. The key to homes safety is in the wiring. For example, the panels will host all wiring options in one panel instead of hosting just one cable outlet of the same size. Home safety technology has not made much progress in the past. However, it seems that it is starting to become a reality now as companies are taking part in the Home safety industry.

            Home safety technology[6] offers the prospect of significant improvements in living standards for everyone including older or disabled people who are heavily reliant on home care. Home safety is a home emphasizes on safety, security and comfort with modern technology in it.

            According to Lim et al. [9], almost half of those surveyed (45%) are interested in having the sort of functions offered by a Home safety. The reason consumers embrace the idea of smart home technology is because of the safety and security features it after, which according to statistic, was agreed by about 70% of respondents.

           

A study by [1]the main idea is about the new generation of homes. Home safety are actually ordinary homes turned extraordinary using the latest technology. A smart home is nearly fully automated and it ensures safety, security and comfort for everyone under its roof. By utilizing advance and complex technologies, life is made easier and simpler.

            Home safety offer the best in security, safety and comfort. It was originally instead for the technologically inclined (techno geeks) but now, Home safety are aimed at the general public. This is because Home safety make everyday responsibilities easier and simpler, besides saving time and energy. Home safety prove especially convenient for those who have hectic lifestyle, aiding them in the daily house chores by [3].

A Home safety provides benefits to the home owner as it ensures the safety and security of the family members, simplify house chores and tasks and helps in efficient energy management, thus reducing energy bills for the home. Automation helps make a Home safety more convenient. Safety and security features are installed in and around the house. For example, sensors that are installed can detect a person’s movement and activates a certain preset function by [7]. This would prove extremely useful when the home owner is not at home or outstation. Any sign of break-ins would be detected immediately and the alarm would be let off.
