The Python request library periodically uploads temperature information to the yeelink platform and modifies RC. the local script enables the Python script to run in the background at startup, and reports the temperature information to the platform every 5 minutes. I have read a lot of blog posts about
operationFirst, warm up through shell operations. Log on to Raspberry Pi and run the following command to view the CPU temperature: # Enter the directory CD/sys/class/thermal/thermal_zone0 # view the temperature cat temp # Raspberry Pi returns 48692 from the above operations you can get the following [1]
of the CPU is detected and written into the system files, and timed refresh. The specific path to this file is/sys/class/thermal/thermal_zone0/temp, which is a read-only file. We only need to access this file to get the current CPU temperature. Viewing through the graphical interface is simple and only provides a way to view it using terminal commands.Enter the following command at the terminal:
Cd/sys/class/thermal/thermal_zone0
After entering the directory where the temp file is located, ente

There are many common Linux system branches in China:
1. Debian
2. RedHat

How to Use image effects on Raspberry Pi
Now you can use the Raspberry Pi camera module ("raspi cam") to add a variety of image effects to your photos, just like using a card camera. The raspistill command line tool provides a wide range of image effects options for Raspberry

In the previous article "Raspberry Pi's Application in ID card verification", I briefly introduced and implemented the function of Raspberry Pi's reading with ID card. However, reading the local machine is far from enough.
The retrieved ID card information is sent to the remote backend server over the network for data query, judgment, and storage.
