การสื่อสารข้อมูลความเร็วต่ำผ่านสายส่งกำลังโดยใช้ไมโครคอนโทรลเลอร์ (Low Speed Data Communication Based on Power Line Communication Using Microcontroller)

Abstract

This paper presents a low speed data communication through power line cable using microcontroller. This article will analyze a noise level within a grid to determine the appropriate frequency of the carrier. Then, the frequency is used to design the transmitter and receiver circuit with low cost and can be connected to microcontroller directly. The experimental results show that the transmitter and receiver circuit then offer good without disturbing problem.
