[July 2022 to August 2022]      Hands-on experience in PLC programming using EcoStruxure Machine Expert (Modicon M221). Developed SCADA applications for industrial monitoring using Ignition SCADA platform. Designed Human Machine Interfaces (HMI) with Vijeo Designer for real-time plant control. Worked with industrial sensors, actuators, and communication protocols (Modbus, Ethernet/IP). Configured Variable Frequency Drives (VFDs) for motor speed control applications. PROJECTS DONE: Title : IoT Based Coal Miners Safety Jacket Using ESP32 Abstract  The jacket is equipped with sensors to detect critical parameters such as toxic gas levels (e.g.,     methane and carbon monoxide), temperature, and humidity. Wireless communication is achieved using the HC-12 433 MHz module, enabling reliable data transmission within a range of approximately 1 kilometer. A centralized control room setup is equipped with an LCD display to monitor miners' safety data in real time. The system generates alerts when unsafe conditions are detected, ensuring timely intervention. The project demonstrates the potential of IoT in creating a safer and more efficient working environment in the mining industry. Title : PLC-Based Automatic Water Tank Management System with SCADA Abstract      The system automates the monitoring and control of a three-phase motor used for water pumping based on real-time sensor data. A float sensor is employed to detect the water level in the tank, ensuring that the motor does not turn on when the tank is full. To verify whether the motor is actually running, a flow sensor provides feedback, preventing false activations due to electrical faults or dry-run conditions. The motor is controlled via two relays, which are connected to a starter for safe operation, the system allows manual control of the motor based on the water level of the tank, but the system restricts the pump from turning ON if the tank is already full. The entire system is integrated with SCADA for real-time monitoring, control, and alarm notifications, enhancing operational efficiency and reducing the risk of overflow or dry-run damage.
