New Davis sensors, Sept 2017
The original weather station was an OS WMR-200. By 2017 two of three sensors had failed and reliabilty was an ongoing problem. I therefore bought a new, better weather station, a Davis VP2, and installed its sensors. I also took the opportunity to clean and re-paint the radiation shield
