MediBox: Smart Medicine Storage System

Welcome to the MediBox repository! This project aims to provide a smart solution for storing medicines securely while also monitoring environmental conditions such as temperature and humidity. The system consists of a hardware setup using ESP32 module, DHT22 sensor, OLED display, and push buttons, along with a Node-RED dashboard for data visualization and control.

Hardware Components

• ESP32 Module: Acts as the main controller for the system, handling sensor data and user inputs.
• DHT22 Sensor: Measures temperature and humidity levels inside the MediBox.
• OLED Display: Provides visual feedback to the user, displaying information such as current time, set alarms, and environmental data.
• Push Buttons: Used for user interaction, allowing users to set time, alarms, and navigate through the menu.

MediBox Circuit Setup

Here is the circuit setup for the MediBox:

Functionality

• Set Time: Users can set the current time using the push buttons.
• Set Alarms: Up to 3 alarms can be set for medicine reminders. Users can adjust the alarm times using the push buttons.
• Temperature and Humidity Monitoring: The DHT22 sensor continuously monitors the temperature and humidity levels inside the MediBox. If the levels are outside the specified range, appropriate alerts are displayed.
• Node-RED Dashboard Integration: Data from the MediBox, including temperature and humidity readings, are sent to the Node-RED dashboard using MQTT protocol. Users can visualize the data and adjust the light condition in the MediBox as needed through the dashboard.

Node Red Dashboard Design

Repository Structure

• hardware/: Contains the code for the ESP32 module and hardware setup.
• node-red/: Includes the Node-RED flows and configuration files for the dashboard setup.
• docs/: Documentation files, including this README and any additional guides or manuals.

Getting Started

To replicate this project, you will need the following:

• ESP32 module
• DHT22 sensor
• OLED display
• Push buttons
• Wokwi platform for hardware simulation
• Node-RED for setting up the dashboard

Follow the instructions in the respective directories (hardware/ and node-red/) to set up and configure the hardware and Node-RED dashboard.
