Abstract
The main objective of the project is to develop an iot based electricity meter reading displayed for units consumed and cost there upon over the internet. A digital meter whose blinking LED signal is interfaced to microcontroller through LDR the blinking LED flashes 3200 times for 1 unit the LDR sensor gives an interrupt each time the meter LED flashes to the programmed microcontroller,micro controller takes this reading and displays the it on an LCD duly interfaced to the microcontroller.the reading of the energy meter is also sent to Ethernet shield module being fed from the micro controller via level shifter ic and RS 232 link which transmit data directly to a dedicated web page for display any where in the world. 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.
