Power failure may be caused by various factors: an overload on the power plant, a thunderstorm, cable breakage during excavations. Whatever the reason you will be notified as soon as the power failure occurred in your remote area and you can act accordingly.
This device notified the user when the remote power off condition has occurred. It is an intelligent device iSocket, which has a power off alarm function. This smart device is designed for remote control devices. You can command remote power on, remote power off via an SMS or a phone call. As soon as the system experiences power failure you will receive a power failure alarm.

CHAPTER ONE
1.1 INTRODUCTION
In modern society, it is impossible to imagine life without electricity. Modern equipment requires a continuous supply of electricity. Not only industry, but also in the household. Take the case of an ordinary refrigerator. If you experience a power off situation, your food will be spoilt. But much more important, what if the power failure "spoils" your business. For example, uninterrupted power supply is needed for your server, which manages your accounting programme or provides uninterrupted operation of your website.
Of course, in most critical applications, uninterruptible power supplies (UPS) are used, but this is not always the case. Also, these devices cannot provide continuous operation in the event of remote power off. Often you need to take other action according to the situation. But how do you know that the remote site has experienced a power off condition?
This electronic device answered the question. This device notified the user when the remote power off condition has occurred. It is an intelligent device iSocket, which has a power off alarm function. This smart device is designed for remote control devices. You can command remote power on, remote power off via an SMS or a phone call. As soon as the system experiences power failure you will receive a power failure alarm.
1.2 OBJECTIVE OF THE PROJECT
The objective of the project is to design a power supply monitoring device that will trigger a buzzer when the mains supply cuts off. Once the buzzer sound, one will know that there is a loss of power supply and actions need to be taken to rectify the situation by providing alternative power supply or relocating the installation.
1.3 SIGNIFICANCE OF THE PROJECT
A failure in the power supply to some people causes only a irritant, they may have to reset a clock, but to other people especially business, they can and do cause thousands of pounds of damage.
This damage may be in the form of lost food in a fridge or freezer, amounting to hundreds of naira of lost stock, it may be chemicals, medicines, and electronics.
A power cut may have cut the heater off in the greenhouse, a fan off in a computer room, it may have caused a computer to fail, there are hundreds of reasons that you need to know if there is or has been a power failure. This device is designed to inform you when the power has failed.
1.4 CONSEQUENCES OF A POWER FAILURE
- No lights in the house
- Loss of refrigeration – food spoils
- No heat or air conditioning
- No flushing toilets or running water
- Can’t cook on electric range or in microwave oven
1.5 APPLCATION OF POWER FAILURE ALARM
Typical uses of power failure signal include monitoring:
* fridges/freezers;
* fish tanks/aquariums;
* sump pumps;
* computer equipment;
* heating systems;
* chemical storage;
* and many other applications.
1.6 SCOPE OF THE PROJECT
This project is a power supply monitoring device that will trigger a buzzer when the mains supply cuts off. At the same time, the light emitting diode will be turned ON. This device is helpful to inform the loss of power supply to some critical installation such as a pump in a fish tank. Once the buzzer sound, one will know that there is a loss of power supply and actions need to be taken to rectify the situation by providing alternative power supply or relocating the installation.
1.7 LIMITATION OF THE PROJECT
It is true that it is said “everything that has advantages also will have disadvantages,” but for the case of this project, the only limitation is that it causes disturbance. When the alarm blows it causes distraction. Even at the middle of the night when there is power restoration/ power supply, the alarm will distract one’s sleep.
1.8 PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this work is on the introduction to power notification from isocket. In this chapter, the background, significance, objective limitation and problem of power notification from isocket were discussed.
Chapter two is on literature review of a power notification from isocket. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
