Oregon Weather is an app for the Mac that uses a USB RTL-SDR dongle to receive temperature and humidity data from Oregon Scientific THGR122NX temperature/humidity sensors (version 2.1 of the Oregon Scientific protocol). The code can be easily extended to receive other v2.1 Oregon Scientific sensors.
The code is dependent on these libraries:
- RadioTools (my DSP library). (https://github.com/enlarsen/RadioTools)
Both libusb and the rtlsdr libraries and headers can be obtained from Brew.
brew install librtlsdr
This will also install the libusb dependency.
