To anticipate the outage, in this final project I will make ATS (Automatic Transfer Switch) by using arduino program the data communications system receives and sends the commands to the circuit for moving the electrical home from PLN to the generator generator and vice versa, and then before the switching , GSM sim800l will send short message information via SMS smartphone the user, with in obtaining this automatic message then we can know information about genset in this simulation tool presented in genset instead of indicator light.Teknik ElektroElektronikaEngineering and Allied Operations (Teknik dan Ilmu yang Berkaitan)Economics (Ilmu Ekonomi)Management and Auxiliary Service (Manajemen dan Ilmu yang Berkaitan)Thesis
