Perancangan dan pembuatan alat transmisi data jumlah pemakaian beban listrik menggunakan radio frequency (RF) (CD + Cetak)
Technological progress and growth specially area of electronics and computer very fast. Growth non-stoped tobe conducted and innovated to keep abreast of era. Insufficient certain technological type of defensire long as new comer. Commutation of technology in structing to more dot go forward automatically also can improve quality live technological consumer.
See from a bove background, hence the writer wish to design and realize a kitt wich can be transmiting or receiving data the among in summery used Kwh meters throw RF freckwensi , as an alternative way in writing data as an alternative way in writing data of Kwh meters, in manualy so can reduce error writing data, in crease by uses in RF freckwensi as media by transfer data.
This appliance is designed with a few the especial component and module like Frequency TLP-RLP Radio 434A, IC HT12D, IC HT12 E AT89C51, type TIP31A transistor, and Relay 12 V and also some other supporter component. For the Frequency TLP-RLP Radio module 434 A use Amplitude shift keying transmission system ( ASK) assisting in acceptance sinyal data and emission in the form of wave amplitude signal from coding by IC HT12D and HT12E to lesson the happening of noise.
