Abstract:

 The main objective of the project is to develop an energy meter to know the exact billing that each load is going to consumed with wireless technology.

For this research work we had taken a energy meter and is connected to an Opto-coupler, which counts the led that glows (depending upon the requirement we can increase the led glowing on/off time pulses), so its gives an interrupt after every time set by us is given to a programmable micro controller of 8051 family, The microcontroller takes the reading from the energy meter via an Opto-isolator and displays the reading on the LCD duly interface to a microcontroller. The reading of the energy meter is also sent to the cell phone of the user by a message through GSM modem being fed from the microcontroller via level shifter IC and RS232 link. The desired number is auto saved on the microcontroller over a missed  call.

 The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

 

The price is around rs.9700. For more details please go to edgefxkits.in
