Recently programmer Erik Larsen wrote in to us to let us know about a MacOS application he has been developing to receive temperature and humidity data from Oregon Scientific v2.1 sensors. Oregon Scientific manufactures popular electronic weather stations that transmit data from remote sensors wirelessly. Using an RTL-SDR and Eriks software it is possible to receive the weather station data on a Mac computer and display the data on a GUI. The software can be downloaded from the releases section on its GitHub page.
Note that there are also several Linux based Oregon Scientific decoders available including rtl-433m-sensor, rtl_osv21, and rtl-wx.
