The proposed paper is designed to measure various parameters of a solar cell, such as light intensity, voltage, current, and temperature, through multiple sensor-based data acquisition methods. A solar panel is employed to track sunlight, with a PIC microcontroller serving as the central processing unit. The system utilizes an LDR (Light Dependent Resistor) sensor to measure light intensity, a voltage divider circuit for voltage measurement, a current sensor for current detection, and a temperature sensor to monitor temperature levels. These parameters are then processed by the microcontroller and displayed on a 16x2 LCD screen. The light intensity is measured via the LDR sensor, voltage is determined using the voltage divider principle, current is sensed by the current sensor, and temperature is tracked by the temperature sensor. The power supply consists of a 230V/12V step-down transformer, which reduces the voltage to 12V AC. This AC voltage is converted to DC using a bridge rectifier, with ripple smoothing provided by a capacitive filter. The output is then regulated to 5V using a 7805 voltage regulator, which is required for the operation of the microcontroller and other associated circuits.
