6 FAQs about [LabVIEW Solar Tracking Control System]
What is a virtual instrumentation system based on LabVIEW and Arduino?
This project presents a simple virtual instrument system based on LabVIEW and Arduino to characterize and monitor a PV panel. This project proposes a low-cost real-time virtual instrumentation system based on LabVIEW and Arduino to characterize a PV panel. Also for monitoring its output data (current, voltage, and power) under real condition.
How are the parameters of solar panel measured?
The parameters such as voltage, current, light intensity of solar panel are acquired continuously. Voltage is measured by using voltage divider, current is measured by using acs712 and light dependent resistors (LDR) is used for capturing maximum light source and the acquired data are processed in Arduino and send to LabVIEW.
What software is used to design a solar PV system?
Arduino IDE, LabVIEW, and LIFA are used as the software of the system design. The Figure below shows the schematic diagram of the instrumentation system. The current and voltage sensors sense the output current and voltage from the PV panel. Then, the readings of the two sensors are transmitted to the microcontroller of the Arduino UNO board.
How to send data from Arduino to LabVIEW?
To send data from Arduino to LabVIEW, the LIFA is necessary to make the connection between the Arduino microcontroller and the computer. For this, you just need to follow the following steps: + Install the LabVIEW software (LabVIEW 2011 or later); + Download the NI-VISA drivers and install it.
What is LabVIEW interface for Arduino?
Then, the readings of the two sensors are transmitted to the microcontroller of the Arduino UNO board. While the LabVIEW Interface for Arduino (LIFA) serves as an interface between the Arduino microcontroller and computer to make communication between the microcontroller and LabVIEW through a serial connection.
How a PV panel's output power reading is done?
The PV panel's output power reading is done out by the product of the current and voltage reading. Finally, in the last part, the I-V and P-V curves of PV panel characteristics will be plotted in the monitoring interface of the system by using x/y graphs in the LabVIEW palette.
