Integration of Sensors and Solar Power

In the previous chapters, we discussed using a solar panel to provide a steady 12 V direct current power supply day and night, along with a rechargeable battery and a solar controller. A step-down voltage converter was used to reduce the input voltage to the Arduino board, minimizing heat dissipation for long-term deployment. We also worked with the GPS, LCD, SD card, and BME280/BMP390 sensors connected to an Arduino UNO board. Now, it's time to integrate these components to create a solar-powered device that can continuously record weather data, including air temperature, humidity, barometric pressure, time, latitude, and longitude.
