Elva 🚪🔋

IoT Access Control Project with Energy Metering

Overview

Elva is an IoT-based access control system for elevators, utilizing wireless key fobs for user authentication and tracking energy usage per user. The system also provides an admin panel for efficient management.

Elva is built on the powerful combination of:

• ESP32
• ATmega328P (with Arduino Bootloader)

The system interfaces with the following components:

• RTC Module
• SD Card
• Current Transformers
• Differential analogue measurement circuit for AC
• Solid State Relays (SSR)
• Additional circuits like a voltage divider (from 5V to 3.3V) and more.

🚀 How to Set Up

Requirements:

• ESP32 and ATmega328P microcontrollers.
• RTC Module, SD Card, Current Transformers, SSR, and supporting circuits.
• Circuit board (PCB) or breadboard setup for assembly.

Notes:

• The provided code covers the ESP32 only but below is the link to the another needed repo.
• U need to have a good expertise with arduino and Esp32 to continue the steps below and figure out the connections from the code in this repo. I will be adding more files and the connections later.
• Additional components and setup steps are required for full functionality.
• Integration with the elevator electrical system is necessary for measurement and control.

Steps:

1. Assemble the hardware components:

   • Follow the provided circuit designs (to be added in future updates).

2. Program the ESP32:

   Upload the ESP32 code using your preferred Arduino IDE, PlatformIO or ESP32 toolchain.

3. Program the ATmega328P :

   • Upload the code from my repo PowerMeterSerial3 using your preferred Arduino IDE, PlatformIO or ESP32 toolchain.

4. Write web files and db file to SD card:

   • Contact me for these files and to help u with configuring everything

5. Connect the system to the elevator:

   • Ensure proper wiring with the electrical system.

6. Test the setup:

   • Verify communication between the ESP32, key fobs, and energy measurement components.
