Electric Field Meter

INRODUCTION

What is the EMF? EMF mean is Electromotive force. EMF refer to voltage generated by a battery or by the magnetic force according to faraday’s law, which states that a time varying magnetic field will induce an electric current. Electromotive “force” is not a force but a potential, or energy per unit of charge, measured in volts. Formally, EMF is the external work expended per unit of charge to produce an electric potential difference across two open-circuited terminals. The electric potential difference produced is created by separating positive and negative charges, thereby generating an electric field. The created electrical potential difference drives current flow if a circuit is attached to the source of EMF.

OBJECTIVES

• Identify EMF area 
• Determine the strength of Electric flux strength 
• Ghost hunting 
• Preventing from biological bad effect

Internal Amplifier Circuit

Circuit Diagram

Above amplifier circuit directly connecting to the microcontroller and then after calibrating electric field strength display in the LCD.

Antenna

There are various kind of antenna available in the market.  normally in domastic distribution lines frequency range is around 50Hz. there for I built an antenna which suitable for that range.

Available antenna in the market

Future plans – Increased the sensitivity.

 

Smart Power Socket

Home automation has been very popular concept today. but as a third world country it is very strange thing to our people. as well as it will take to high cost to make your home automated. but it will be no longer problem. this smart socket is simple socket that can easily  plug and use. but it can be introduced as the next level of wall socket. this smart wall socket has ability to control over internet in any where in the world. it has amazing features.

Conclusion
IOT is the very popular technology in the world. Using this technology there are lot of home automation system were invented and it won’t stop. There are lot of smart production have introduced to people which increase human life comfortability. Smart switches are also have made big influence to the people. Nowadays people are highly using smart switches and smart other technologies. I think this smart socket will also help full to people to increase their comfortable life. Also in day to day life with their busy life cycle they made lot of mistakes. Some time they are forgotten switch of the iron, water motors, and heaters due to their busy life. I think for those situations this product will be really help full to people to manage their day to day life in effective manner.

Future Direction
This product could be reduced in size and also can added more power outlet in one socket. Also supposed to include USB power outlet. As well as we are looking for more tiny and attractive production rather than current product. Also we suppose to add calendrer that can on and off ability on particular day. Also it’s need to increase the sensitivity of power socket and also should upgraded to true RMS detector to reduce power recoding error. Also supposed to add voltage sensor. Moreover can be link together more power sockets with one web page. Also I supposed to built Android application Also.
