Detailed Working of Arduino-Based System for Monitoring Electrical Parameters with MATLAB and GPS :

The Arduino-Based System for Monitoring Electrical Parameters with MATLAB and GPS is designed to measure, display, and log various electrical characteristics while concurrently providing real-time geolocation data. This detailed description will walk you through how the circuit operates, capturing and translating electrical parameters into insightful data, which is then interpreted and presented by MATLAB and GPS module.

Our journey begins with a 220V AC main supply which is stepped down to 24V AC using a transformer. This stepped-down AC voltage is further rectified by a bridge rectifier circuit. The rectified DC voltage is then filtered using a capacitor to provide a steady DC output. To achieve regulated voltages, the rectifier's output is fed into two voltage regulator ICs, the 7812 and 7805, which produce 12V and 5V DC outputs respectively. These regulated voltages are crucial as they power the various components used in our system, ensuring they function correctly and protect them from voltage fluctuations.

The heart of the circuit is the Arduino Mega microcontroller which acts as the brain of the project. All the sensors and modules are interfaced with this microcontroller. Connected to the Arduino are the sensors which measure the voltage, current, and power used by the external load, in this case, a bulb. The voltage sensor module detects the voltage across the load, converting it to a readable value for the Arduino. The current sensor module measures the current flowing through the load, again providing a readable value to the Arduino. These two readings are used to calculate power consumption by the load.

Additionally, a GPS module is connected to the Arduino which logs the geographical location data. The GPS module continuously feeds real-time location data to the Arduino, which processes and sends this information along with the electrical parameters to MATLAB. This coupling of electrical data with precise location data provides a comprehensive overview of where and how the power is being used.

A 16x2 LCD display is also incorporated into the system to provide real-time feedback to the user. This display shows live readings of the electrical parameters, such as voltage, current, and power, giving immediate, on-location insight. The potentiometer linked to the LCD screen is used to adjust the display contrast, ensuring readability in various lighting conditions.

The Arduino continuously reads the sensor data and processes it. For instance, the analog values from the sensors are converted to corresponding voltage and current values using predefined calibration factors. These values are then used to compute the power consumption using the formula:

Power (Watts) = Voltage (Volts) x Current (Amperes)

All this data, once processed, is sent to a connected computer running MATLAB. MATLAB acts as a data logger and analysis tool, storing the incoming data and providing detailed analysis and visualizations of the power usage over time. This information is crucial for optimizing power consumption and identifying usage patterns.

Lastly, the GPS functionality amplifies the utility of this system significantly, making it especially useful in mobile or distributed systems where knowing the exact location of power usage is critical. The GPS and power data fusion can be utilized in various applications like smart grids, remote monitoring systems, and other advanced power management solutions.

In summary, the Arduino-Based System for Monitoring Electrical Parameters with MATLAB and GPS is an intricate network of components working harmoniously. The project's design ensures that electrical parameters are accurately measured and logged, while MATLAB processes these data to offer insights. Simultaneously, the GPS module provides real-time location monitoring, making this system a comprehensive tool for advanced electrical parameter monitoring and analysis.
