RTL-SDR as Oregon Scientific sensor sniffer

Many Oregon Scientific do not have any PC interface (they are present in WMR200 or I-900 but usally not available in cheaper ones). Their radio sensors transmit on 433.92 MHz sending data packets containing the data every 30 seconds using OOK and manchester encoding for 32 bits of data.
Kevin Mehall wrote Python script that decodes radio signal trasmitted by Oregon Scientific and captured with RTL-SDR (DVB-T tuner working as SDR hardware).
