The last time we had already shown how a DVB-T Stick with RTL-SDR drivers Installed. Today, we want to put the amount in order to get tendon how easy we first results with our Stick can. We will try to receive various devices in the 433Mhz range, and try to find out whether a neighbor is so kind, and give us his weather data. To do this, we clone the returned Code from git, compile with cmake and install the module.
First, we connect again via SSH to our Raspberry what we, in the meantime, "rasp" have called, we connect so as to "pi" at the "rasp" Syntax: "ssh pi@rasp"
After the Forced Update/Upgrade we will check whether the necessary dependencies are present: "sudo apt-get install libtool libusb-1.0.0-dev, librtlsdr-dev rtl-sdr"
With "git clone https://github.com/merbanan/rtl_433.git" let's get the Code:
Is the Download complete we change with "cd rtl_433" in the newly downloaded directory, create the folder build with "mkdir build" and switch with "cd build/" in the path. After compiling with "cmake ../" we see the following output:
In the connection we can already "make" and "sudo make install" run.
And after the change to the main directory with "cd ~" the program "rtl_433 -G" run.
And find right away a Sensor:
A redirection to a file is without a lot of effort, a distribution of the values via MQTT to a Broker such as Mosquitto is conceivable. And what sparks you?
