raspberry pi measure temperature

files from a remote server.My other Raspberry Pi was once used as my git repository. To tell the truth, the memory was a little too powerful, installing and deploying gogs through docker is the most agile way to build a git repository. Of course, I will also bring a temperature and humidity sensor to the old employee and push it to the server through websocket.

This book is divided into 18 chapters, the first 3 chapters are the basic chapters of the book, the main introduction of the Raspberry Pi some basic conditions and basic operations, to let readers understand the past life of Raspberry Pi, master the basic use of Raspberry

At first, there were a lot of problems: 1. The Raspberry Pi system burned incorrectly, and it wa

first, the simplest method on the Raspberry Pi is to use apt-get and then give control to the Openhab user.sudo apt-get install openhab-addon-binding--hr Openhab:openhab/usr/share/openhabNext, you need to tell Openhab to load the binding and configure all the required variables. go to the configuration folder, copy a copy of Openhab-default.cfg, and name it openhab.cfg. Open the file, search for hue, and r

Some time ago, cgminer was set to start when it was started. Due to various problems, the system was not very stable and it was stopped from time to time. I checked it online, and Raspberry Pi immediately tried the hardware guard function, which basically solved my problem. ? The principle is simple: Watchdog requires heartbeat) If no data is fed within the specified time period (15 seconds by default), the

" and he found a way to solve it. And my approach is to migrate the system to Openelec. This is something.Third, the use of TV remote control kodiCec:consumer Electronic control, literal translation into consumer electronics. It provides the use of remote controls to control devices connected via HDMI. And our Raspberry Pi and RASPBMC systems have been supported from both hardware and software levels. The n
