This post was last edited by Feiyangzizi on 2019-1-3 16:15 Following the air quality sensor , we continued to work. This time, we added a Gyroscope to the original one for display, and the data of CCS811AirQuality was transmitted to the mobile app and cloud server as Bluetooth. 1. Set up the IOT end. I won’t say more about the settings of other components. What needs to be noted here is the Bluetooth address setting, which must be the address of the IOT on hand, otherwise it will not be connected, you must pay attention, you must pay attention. .
I have encountered another problem here and would like to see who can solve it
. When doing Gyroscope display, three data will be displayed, xyz, but the IOT screen can only display the middle data completely, and the other data are not displayed completely. I don’t know how to modify it...
Below are all the components of IOT.
2. Set up the app When setting up the app, you need to design the interface, so you still need a certain amount of artistic talent. I don’t have any artistic cells, so I just put it somewhere randomly. As long as it can be displayed, it’s fine.
The final display effect is shown in the figure below
3. Set up cloud service In fact, the cloud service settings are very simple. Just connect the cloud upload of the app to the database directly.
4. Test photos and videos A. App data test
A test video
app test data display B, cloud test
A video of testing cloud data, the update is a bit slow
The cloud updates very slowly The next step is to continue to improve this system and eventually make it into a weather monitoring station. . . .
