Hydrology Master is online. Today is a water electronic lunar calendar card.
First of all, let’s talk about electronic accessories. One is the choice of small electronic screens. When encountering a lot of text, especially Chinese characters, don’t choose the traditional 128x64 oled. The above can be seen clearly). I chose ili9341 and thought it was convenient.
Secondly, the room temperature does not use api to grasp the local weather, but uses hardware temperature measurement. Here is the ds18b20. I found that this thing is quite advanced. The accuracy is still good, and the accuracy in the normal temperature range is already very high. It should be noted that its protocol is 1-wire (that is, w1-gpio must be initialized on the board).
As for the relevant information of the lunar calendar, it is captured by the api. Next, send a code journal.
