As receiving the electricity meter reading is quite a complex work in India because the person use to go every house and note the reading so the main objective of the project is to receive the reading via SMS to save manpower and time.
Video to easy understand
1) Power Supply Design
It is designed by using 2 pin power plug then the transformer 12 - 0 - 12 which will step down the 220 v ac to 12 - 0 - 12 ac which is converted to DC voltage using bridge rectifier section having diode in4007 and capacitor 1000uf and voltage regulator 7805.
2) Electricity Meter for Reading
One electricity meter is taken for reading
The meter that is used here is single phase meter which is not the standard meter and tempered to make the project
So it can't be used directly at homes until the project has been finalized by the government laws.
3) Device for updating reading
One device should be connected to meter, so the reading should be updated at regular intervals.
4) GSM Modem
As we are making the system to receive SMS and transmit it, so a GSM modem should be connected to do the required task.
5) Controlling Section
Controlling section is used to update the value and store it in EEPROM memory so it can be transferred through SMS.
The controller section also verifies the SMS and send the feedback sms on the same number from which it received the SMS.
