Abstract :
To optimize and facilitate the control of electric pulses for prepaid KWH
users from avoiding disconnection in the electric energy supply, a prepaid KWH
monitoring system is designed using SMS gateway. This prepaid KWH monitoring
system is very helpful for electricity customers to find out the remaining usage of
electrical energy so that customers can directly add electricity. Electrical energy
monitoring system by entering a token value of 20 watt hour and the load used by
a 30 watt fan can be used for 24 minutes 27 seconds. The SMS gateway system
will send a notification if the token stays 5 watt hour so that the electrical energy
is added immediately.
