Arm Based Smart Single Phase Energy Meter With Automatic Bill Generation And SMS Alert
A cost effective novel single phase digital energy meter is developed with the help of an ARM based
microcontroller which is capable of calculating true values of active, reactive and apparent power, power factor, Total
Harmonic Distortion (THD) and energy consumed. The designed meter is simple, portable and easily reconfigurable
according to specific needs.
The parameters calculated are transmitted to the billing station through wired means of communication thus eliminating the
need for the utility personnel to visit each home individually for noting the meter readings/generating the bill. This data gets
logged in and is used for generating bills and can also be used for analysis in order to improve the power quality and
understand the load and usage pattern.
The detailed bill generated can be mailed to the customer’s Email ID and minimal information extracted from this bill can be
sent to the user’s registered mobile number automatically via SMS.
