Energy Meter Per Hour Average Max And Min Load Display On LCD

Now days there is rapid increase in the power consumption, which has given rise
to the scarcity in the power generation. There should be an immediate change in this
situation are else the results cannot be even imagined. This not only results in scarcity but
also imposes burden on the common man. This problem can be solved by monitoring the
average power consumption with max and min load which can help the user to monitor
the health status of his load devices as well as to have a control over the power being
consumed daily. This system also helps Transco department to impose tax if the average
power consumption per hour is more than the prescribed level by which we can control
the consumer from wasting the power.

So our aim in designing this device is to fulfill the multiple purposes of the
consumer and finally impart a control over the power consumption so that there will not
be any hazardous results in the near future due to the power scarcity. The device input
and output modules are controlled with help of a micro controller, which can be termed
as a control unit for the entire system. The energy meter is interfaced to the
microcontroller with the help of an interfacing circuit. This interfacing circuit is
something similar to a counter, which is capable of counting the pulses with respect to the
power consumed by the user. The microcontroller takes the responsibility to count these
pulses and derive the equivalent average, Min and Max loads for that hour duration. The
amount of power consumed is displayed on this LCD. In addition to this the controller is
also interfaced with few LED indicators.

The design of this system is very much sensitive and should be handled with
utmost care because the microcontroller is a 5 volts device and it is employed to monitor
the household power consumption per hour where it should be interfaced with a 240 volts
energy meter. So every small parameter should be given high importance while designing
the interfacing circuit between the controller and the energy meter. The major advantage
of this system is its reliability to operate and a user-friendly output.

This project provides us with the learning’s on the fallowing aspects:

1. Interfacing Energy Meter with Microcontroller.
2. Counter module implementation.
3. LED and Buzzer Interfacing.
4. LCD Display Interfacing.
