rtl_433 turns your Realtek RTL2832 based DVB dongle into a 433.92MHz generic data receiver
Compiling rtl_433 requires rtl-sdr to be installed.
Installation using cmake:
cd rtl_433/
mkdir build
cd build
cmake ../
make
make install
Installation using autoconf:
cd rtl_433/
autoreconf --install
./configure
make
make install
rtl_433 -h
Usage: [-d device index (default: 0)]
       [-g gain (default: 0 for auto)]
       [-a analyze mode, print a textual description of the signal]
       [-t signal auto save, use it together with analyze mode (-a -t)
       [-l change the detection level used to determine pulses (0-3200) default: 10000]
       [-f [-f...] receive frequency[s], default: 433920000 Hz]
       [-s sample rate (default: 250000 Hz)]
       [-S force sync output (default: async)]
       [-r read data from file instead of from a receiver]
       [-p ppm_error (default: 0)]
       [-r test file name (indata)]
       [-m test file mode (0 rtl_sdr data, 1 rtl_433 data)]
       [-D print debug info on event]
       [-z override short value]
       [-x override long value]
       [-R listen only for the specified remote device (can be used multiple times)]
       filename (a '-' dumps samples to stdout)

Examples:
| Command | Description | 
|---|---|
rtl_433 -a | 
will run in analyze mode and you will get a text log of the received signal. | 
rtl_433 -a file_name | 
will save the demodulated signal in a file. The format of the file is 48kHz 16 bit samples. | 
rtl_433 | 
will run the software in receive mode. Some sensor data can be receviced. | 
This software is mostly useable for developers right now.
