Medicine Reminder With Telegram Notification

Smart Medicine Reminder with Telegram Notification Report

1. Introduction

This project describes a smart medicine reminder system designed to assist users in adhering to their medication schedule. It utilizes an ESP32 Wi-Fi module for internet connectivity, an LCD module for displaying information, a DS1307 RTC module for accurate timekeeping, an HC-05 Bluetooth module for potential future functionalities (optional), a 12V power supply, a limit switch for medicine box detection, and a servo motor for automated medicine box opening. The system boasts the following features:

• Automated Medicine Dispensing: The servo motor opens the designated compartment of a medicine box at pre-programmed times.
• Telegram Notifications: Users receive Telegram notifications confirming medicine taken or missed doses.
• Multi-Time Programming: Up to three different medication times can be programmed within a 24-hour timeframe.
• Reminder Alerts: Audible buzzer reminders activate if medication is not taken within a set timeframe.

2. System Design

• Block Diagram: A diagram illustrating the connections between the ESP32 module, LCD module, DS1307 RTC module, HC-05 Bluetooth module (optional), limit switch, servo motor, power supply, and medicine box is included.
• Component Functions:

• ESP32 Module: Processes sensor data, controls the servo motor, and manages communication with the internet (WiFi) and Telegram.
• LCD Module: Displays current time, programmed medicine times, and notification messages.
• DS1307 RTC Module: Maintains accurate timekeeping.
• HC-05 Bluetooth Module (Optional): Allows for future features like mobile app control (not implemented in this version).
• Limit Switch: Detects when the medicine box compartment is opened.
• Servo Motor: Opens the designated compartment of the medicine box based on programmed times.
• Power Supply: Provides 12V power to the system.

3. Hardware Setup

• A detailed explanation of the hardware connections between all components is provided, including pin numbers and clear explanations.
• Wiring diagrams showcasing connections for the ESP32, servo motor, limit switch, and LCD module are included.
• The LCD module type (I2C, SPI, etc.) and its specific connection details are specified.

4. Software Development

• The programming language used for the ESP32 module (Arduino IDE with specific libraries) is explained.
• The code functionalities are outlined:

• Reading the current time from the DS1307 RTC module.
• Comparing the current time with pre-programmed medication times.
• Controlling the servo motor to open the medicine box compartment at designated times.
• Detecting medicine box opening using the limit switch.
• Sending Telegram notifications based on medicine taken/not taken status.
• Implementing a reminder system with buzzer alerts if medication is not taken within a set timeframe (e.g., 30 seconds).
• Including an option for users to program up to three different medication times (within 24 hours).
• (Optional) Utilizing the HC-05 Bluetooth module for future functionalities (not implemented in this version).

5. Telegram Integration

• The process of setting up a Telegram bot for the system is explained, including creating a bot and obtaining the bot token for communication.
• The method for sending Telegram notifications with relevant messages (medicine taken/not taken) is described.

6. Testing and Results

• The testing procedures conducted are outlined:

• Verification of timekeeping accuracy with the DS1307 RTC module.
• Testing of servo motor operation for medicine box opening.
• Confirmation of limit switch detection for medicine box opening.
• Verification of Telegram notification functionality for both medicine taken and missed doses.
• Evaluation of the reminder system with buzzer alerts.

• The observed results are presented, including any encountered challenges and their solutions (if applicable).

7. Conclusion

• The report summarizes the project’s achievements, highlighting its potential to improve medication adherence and user convenience.
• The benefits of features like automated dispensing, Telegram notifications, and reminder alerts are emphasized.
• Future improvements are briefly mentioned, such as incorporating a mobile app for programming and monitoring using the HC-05 Bluetooth module (if desired).
