<Manufacture of solar bench>

The size of the solar panel for receiving solar energy was designed to fit the bench. Since the energy consumed by each function is different, the power consumed by each function was calculated and the size of the solar panel was selected accordingly. Power consumption of LED (lighting), wireless charging, LCD, and Arduino are required for load power of 30W, 10W, 20W, 0.25W, and each usage time is 10[h] because the LED works only at night. In the case of LCD, the actual viewing time was set to 8[h]. In addition, the Arduino to operate the LCD should always be used at 24[h], and the wireless charging was set at 14[h] on the assumption that the maximum use per day. If you calculate and add all the power consumption per day, you get 746[W], and the required solar panel is 746[Wh] / 3.5[h] = 213.14[W] since the average time of daylight in Korea is 3.5[h]. It was expected to be needed. Since it should be used as a standalone type rather than a grid-connected type, it was selected as a panel with a capacity of 240[W] so that capacity was spared.

It is designed to receive weather, time, and temperature information in real time by receiving signals from nearby Wi-Fi and output it on the LCD screen. In addition, the function to indicate the good or bad concentration of fine dust through the remaining amount of the battery and the fine dust sensor is designed in an easy-to-recognize design on the LCD screen.

In order to use the wired/wireless charging function using solar energy, solar energy was converted into electric energy through a solar panel and then charged to the battery. A voltage drop was achieved with a 5V output using a DC-DC converter on the battery, and it was connected to the wireless charging module. The charging function was used by connecting two other wired ports. At this time, the wireless charging module used a module using the Qi standard. The reason is that the international standard set by the World Wireless Charging Association (WPC) is a magnetic induction method, and since all mobile phones that are currently widely used use a magnetic induction method, Qi wireless charging was used in consideration of versatility.

The LED was controlled using the illuminance sensor and the use of the LED was coded according to the value of the illuminance sensor. It is designed to turn the LED off when the weather is bright, and turn the LED on in the dark evening or at night. Here, when selecting the LED that illuminates the bench, the power consumption is less than about 10W and the LED suitable for the design was selected.

However, since there is a limit to the Arduino voltage when supplying power to the LED, it was directly connected to the battery to supply power. In controlling the LED, the LED was driven by using a TR switching circuit on the digital port of the Arduino's OUTPUT.

A fine dust sensor was used to measure fine dust. After configuring the circuit by connecting the fine dust sensor to the Arduino, the current received from the solar panel was adjusted to the used voltage of the Arduino with a converter. I started the Arduino by writing a code that shows good and bad step by step according to the level of fine dust received from the analog port on the Arduino. After that, this code was printed on the LCD screen using the code displayed on the LCD screen. And according to the good and bad, the fine dust concentration and the change of the emoticon were shown on the screen. After confirming the current concentration of fine dust, people were allowed to take action on future activities.

The battery level check is a function that informs you how much power is left in the battery. First, connect the Arduino to the charged battery using a converter, and then display the voltage change according to the capacity of the battery as a percentage according to the total capacity. I wrote the code. The LCD screen has a more recognizable icon to show how much battery is left. By showing the remaining battery capacity, it is possible to determine whether the mobile phone can be charged by wire or wirelessly in the future, and it was thought that a convenient effect to be checked from the point of view of the administrator could be expected.

To get weather information and temperature by time, I first used the Arduino Wi-Fi shield. In addition, to use this Wi-Fi shield, I wrote a code that connects Wi-Fi and used the RSS distributed by the Korea Meteorological Administration for free to get weather information and temperature by time. After writing this code, it is difficult to receive the weather and temperature every 3 hours by connecting to the neighboring Wi-Fi, and storing the data by receiving the weather information every 3 hours, so I wrote the code to receive the weather on a daily basis. . This data was received and displayed on the LCD screen by combining the code to display the temperature and weather icons on the LCD screen and the codes displayed on the LCD screen. The expected effect of this is that by displaying the weather and temperature on the LCD screen, information can be provided so that people can prepare in advance for outdoor activities.

Regarding the problem of whether strategic power use against bad weather is possible, when the power from the solar panel decreases due to bad weather and the power charged to the battery becomes insufficient, priority is given to each function of the battery to reduce power. You should be able to manage it efficiently. In addition, the question of whether accurate information can be received in real time is to be able to receive RSS information from the Meteorological Agency for one or two days of weather and temperature information and output it in real time at a desired time. In addition, as to whether the function designed with an independent power source, which is a problem, can be smoothly performed, it is necessary to calculate the power consumed by each function from the photovoltaic panel and select the photovoltaic panel so that the function can be performed smoothly with only solar energy will be.
