Embedded C & 8052 Assembly-Based DTMF Appliance Automation

Project Overview

This project implements serial communication between a SIM800L module and an 8052 MCU using DTMF tones. The system enables remote appliance control by interpreting DTMF commands sent from a cell phone to control devices such as LED bulbs.

Key Components & Functionalities

• DTMF Tone Input: Receives tones from a cell phone and extracts control commands.
• 8052 Microcontroller: Processes DTMF tones and executes control logic.
• Appliance Control: Interfaces with appliances (e.g., LED bulbs) to toggle their state.
• IR Sensor Integration: Monitors environmental changes or appliance status.
• SMS Notification: Alerts users via SMS when IR sensor triggers occur.
