- 1. PROGRAMABLE ENERGY AUDITTING EQUIPMENT FOR INDUSTRY FOR INSTANEOUS ELECTRICAL LOAD SURVEY Submitted By Submitted To Gaurav Goyal(15EJCEE034) Mr. Ashok Chundawat Aman Gupta(15EJCEE007) Bhanu Agrawal(15EJCEE025) Bhanu Khandelwal(15EJCEE026) Progress Report on
- 2. This project deals with the calculation of the energy meter billing based on the load consumption given as an input using set up buttons. The microcontroller calculates the rupees that will be consumed by the loads as per the input given and displays it on the 16X2 LCD interfaced with the microcontroller. This project is powered by an on-board power supply takes the ac power and converts it into dc power that is fed to on-board devices and integrated circuits. ABSTARCT

- 7. Why ATMEGA 16 This type of IC can work on low power (5-8 volts). Maximum Frequency at which it can work is 16Mhz. ATmega16 has various in-built peripherals like USART, ADC, Analog Comparator, SPI, JTAG. These peripherals share pins at various Ports of ATMEGA16. For Ex- JTAG port which shares four pins with PORTC. Data Retention: 20 years at 85°C/ 100 years at 25°C
- 8. ENERGY METER An energy or electric meter is a device that measures the amount of electrical energy consumed by a residence, business, or an electrically-powered device. Electric meters are typically calibrated in billing units, the most common one being the kilowatt hour.
- 9. Opto-isolator Opto coupler is a 6 pin IC. It is a combination of 1 LED and a transistor. when light falls on the Base-Emitter junction then it switches pin5 goes to zero. When logic zero is given as input then the light doesn’t fall on transistor so it doesn’t conduct which gives logic zero as output. When logic 1 is given as input then light falls on transistor so that it conducts, that makes transistor switched ON and it forms short circuit this makes the output is logic zero as collector of transistor is connected to ground.
- 10. LIQUID CRYSTAL DISPLAY (LCD) Most common LCDs connected to the microcontrollers are 16x2 and 20x2 displays. This means 16 characters per line by 2 lines and 20 characters per line by 2 lines, respectively. The standard is referred to as HD44780U, which refers to the controller chip which receives data from an external source (and communicates directly with the LCD.
- 11. A RESISTOR IS A PASSIVE TWO-TERMINAL ELECTRICAL COMPONENT THAT IMPLEMENTS ELECTRICAL RESISTANCE AS A CIRCUIT ELEMENT. RESISTORS ARE USED TO REDUCE CURRENT FLOW, ADJUST SIGNAL LEVELS RESISTOR
- 12. A CAPACITOR IS A PASSIVE TWO-TERMINAL ELECTRICAL COMPONENT THAT STORES POTENTIAL ENERGY IN AN ELECTRIC FIELD. Capacitor
- 13. Project The project uses a commercial digital energy meter and derives positive pulses from the same by taking a connection from the pulsing LED. The pulsing LED pulses 3200 times for 1 unit of electrical energy i.e., 1 kilo watt hour. Using push buttons the price for 1 unit and also the time is entered i.e., the time for which the load is to be used. This data is taken and calculated by MC and it displays the rupees which have to be paid for using the load for the prescribed time entered.
- 14. Tentative Result For example if the total pulse detected are 4 then the result can be shown as follows. On LCD we can use formula Pulse* cost of electricity(per KWH.)
- 15. Application It will tell us about the instantaneous load demand. It will also help us in the detection of devices which consume more electricity. Most effective use of this project in keeping check on the load and its management.
- 16. Future Scope • It will help in prevention of the odd devices which consume more electricity. • Proper economic management of the load.
