SmartMachine-Monitor

SmartMachine-Monitor is an IoT-based solution for monitoring electrical machines. It provides real-time data on voltage, current, and temperature, which can be displayed either through a web page or via the Blynk IoT platform.

Features

• Real-Time Monitoring: View voltage, current, and temperature data.
• Web-Based Interface: Access and control the system through a web page.
• Blynk IoT Integration: Use the Blynk app to monitor and control the device.
• Threshold Alerts: Monitor and respond to over-voltage, over-current, and temperature conditions from web interface or Blynk app.
• Relay Control: Toggle relay state from either the web interface or Blynk app.

Components

• ESP32: Microcontroller for WiFi connectivity and control.
• ZMPT101B Voltage Sensor: Measures AC voltage.
• ACS712 Current Sensor: Measures AC current.
• LCD Display (I2C): Displays real-time data on the device.
• Relay Module: Controls electrical devices.
• LEDs: Indicators for various states.
• LM35 Temperature Sensor: Measures temperature.

Code Overview

Web-Based Version (code.ino)

• Libraries and Setup: Initializes necessary libraries and WiFi credentials.
• Web Server Functions: Defines handlers for web requests to serve HTML pages and read sensor data.
• Setup and Loop: Configures WiFi connection and starts the web server. Continuously reads sensor data and updates the display.

HTML Interface (index.h)

• Real-Time Data Display: HTML and JavaScript to update and display voltage, current, and temperature.
• Relay Control: A button to toggle the relay state on and off.

Blynk IoT Version (code_blynk.ino)

• Libraries and Setup: Includes Blynk library for integration with the Blynk app.
• Blynk Functions: Defines virtual pins for data communication between ESP32 and Blynk app.
• Setup and Loop: Configures WiFi and Blynk connection. Continuously reads sensor data, sends it to Blynk, and updates the LCD display.

Setup Instructions

For Web-Based Version

1. Configure WiFi Credentials:

   • Edit code.ino and replace YOUR_NETWORK and YOUR_PASSWORD with your WiFi network’s SSID and password.

2. Upload Code to ESP32:

   • Open the Arduino IDE and upload code.ino to your ESP32.

3. Access the Web Interface:

   • Ensure your device is connected to the same WiFi network as the ESP32.
   • Open a web browser and enter the IP address displayed in the Serial Monitor.

4. Using the Web Interface:

   • View Data: Voltage, current, and temperature are updated every second.
   • Control Relay: Toggle the relay by clicking the ON/OFF button.

For Blynk IoT Version

1. Set Up Blynk:

   • Install the Blynk app on your mobile device.
   • Create a new project in the Blynk app and select ESP32 as the device.
   • Note the Auth Token, Blynk Template ID, and Template name.

2. Configure Blynk Credentials:

   • Edit code_blynk.ino and replace <Blynk Template ID>, <Template name>, and <Auth token> with the values from the Blynk app.
   • Update the ssid and pass variables with your WiFi credentials.

3. Upload Code to ESP32:

   • Open the Arduino IDE and upload code_blynk.ino to your ESP32.

4. Using the Blynk App:

   • Open the Blynk app and add widgets corresponding to virtual pins (V0, V2, V3, V5) used in the code.
   • Monitor and control the device through the Blynk app interface.
