433MHz receiver

Project to intercept transmissions and log data
Last update: 12 August 2018

Signal source:
The outdoor sensor unit of a PanTech WH2950 weather station. The hardware seems to be a re-branded Fine Offset WH2950.


The setup is not peculiar to this model. That has spawned a number of projects to intercept transmissions from various outdoor sensor units. Many of the weather stations look like re-branded Fine Offset hardware, so communications protocols might be similar.
