Industrial IoT (IIoT) Sensor Monitoring System

Description

The Industrial IoT (IIoT) Sensor Monitoring System is designed for real-time monitoring and control of environmental and safety parameters in industrial settings. It integrates a variety of sensors, actuators, and connectivity modules to provide comprehensive monitoring and automation capabilities. This system uses an Arduino microcontroller as the main processing unit, coupled with a Wi-Fi module (ESP8266) for remote data transmission and control.

Benefits

1. Enhanced Safety: Monitors environmental conditions such as smoke, fire, and gas levels to prevent hazardous situations.
2. Real-time Monitoring: Provides continuous updates and alerts to ensure that conditions remain within safe thresholds.
3. Remote Access: Allows operators to monitor data remotely, improving the speed of response to potential issues.
4. Energy Efficiency: Automated control of systems such as exhaust fans and DC motors helps in reducing energy consumption.
5. Predictive Maintenance: Helps in detecting early signs of equipment failure, reducing downtime and maintenance costs.
6. User-Friendly Interface: LCD display provides instant information, and switches allow manual control if needed.

Working

1. Sensors and Inputs:
   • DHT11 Sensor: Measures temperature and humidity and provides data to the Arduino.
   • LDR (Light Dependent Resistor): Detects light levels for automated lighting control.
   • Smoke/Gas Sensor: Monitors air quality and detects harmful gases.
   • Fire Sensor: Detects fire and alerts the system.
   • IR Sensor: Used for motion detection or as an obstacle detection sensor.
2. Microcontroller: The Arduino microcontroller processes data from sensors and manages the control of actuators.
3. Wi-Fi Module (ESP8266): Transmits sensor data to a remote monitoring platform or mobile application.
4. Relay Module: Controls the operation of the exhaust fan and DC motor by switching power on or off.
5. Actuators:
   • 5V DC Motor: Can be used for automation tasks like opening or closing a gate or valve.
   • Exhaust Fan: Activated to control the temperature and air quality.
6. Display and Alerts:
   • LCD Display (16×2): Shows real-time sensor data and status updates for easy monitoring.
   • Buzzer: Emits an alert when critical thresholds are exceeded (e.g., high temperature, smoke, or gas detection).
7. Controls:
   • Switches: Allow manual operation of certain components, such as turning the exhaust fan on or off.
   • Potentiometer: Used to adjust and fine-tune certain parameters such as sensitivity levels.
8. Power Supply:
   • DC Power Adapter: Supplies the necessary power to the entire system.
