I had prepared a case to install the PCB, but it was hard because the interfaces are out of the board. To installed the PCB board to a case, I had to modify it.
In the debugging, I found the display was turned on and had no way to turn it off, it increased the consumption. In order to reduce the consumption and improve the battery life of the weather station, I designed a button to turn off the display screen. At the same time, I deleted the power LED on board. I added a solar panel interface to the board, which can plug the solar panel into it to charge the battery.
