Electricity has a primary importance in life. We can't even think of a day without electricity. How much influence electricity has in our lives. Electricity is the key component of modern technology and without it most of the things we use every day simply could not function and would never have been created. Electricity saves lives and allows people to live longer. So not only are we a more aware and intelligent society, but we have become much healthier. Our lives have improved greatly thanks to electricity, and it is certainly true that most people's quality of life would be significantly reduced and affected if electricity were to somehow disappear. But we have some misconceptions about electrical accidents and some facts about electricity. Young and new workers have a higher risk of workplace injuries than more experienced workers. In this project we are concerned with monitoring parameters such as supply voltage, current, power factor, temperature, humidity, earth resistance, also we aim to provide over voltage protection, over current protection (MCB) along with RCCB implementation, all in a single device also electronically, which decreases response times and provides a greater degree of safety.

Get Original Essay In this project, our aim is to provide industry-level security and monitor the electrical parameters of a house such as supply voltage, current, power factor, temperature, humidity, Earth value. Furthermore, we aim to provide over-voltage protection, over-current protection (MCB) along with the implementation of RCCB all in one device, even electronic, which reduces the response time and provides a higher level of safety. Schematic overview of a total home monitoring system Being a protection device, this device is installed in series with the energy meter as shown below. From now on the device will be called Industrial Security Monitoring Device for Home or ISM Device. ISM System Wiring Diagram 1. Power Input AC power is used to convert to DC power using the Switch Mode Power Supply (SMPS). We get a 12V DC, 1A supply from SMPS which is used to power the entire system. The ground connects to the conceived body. The SMPS can withstand voltage fluctuations and provide smooth DC output. 2. ATmega2560 microcontroller is used to process the parameters of the device. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, a header ICSP, and a reset button. Contains everything needed to support the microcontroller; Simply connect it to a computer with a USB cable or power it with an AC-DC adapter or battery to get started. A0 A1 A2 A3 are analog channel ADC of the microcontroller D0 D1…. They are digital channels of the microcontroller 3. TFT Touch Screen The TFT screen allows you to see the parameters and control the process. It has a resolution of 480 x 320, lifelike 65K RGB colors, TFT screen with integrated resistive touch panel, 4-pin TTL serial interface, 16M Flash memory for user application code and data, integrated micro-SD card slot for firmware update , visual area: 73.44mm (L)?48.96mm (L). Adjustable brightness: 0~180 nits, the range.
