If you haven’t figured out by now, I am a retired meteorologist. I have installed my own weather instruments at my home in Stormstown. My primary station consists of a cluster of sensors for The Davis Vantage Pro 2 weather station.
Pictured is the tipping bucket rain gauge, thermometer, hygrometer, solar sensor, UV sensor and data transmitter. The transmitter has a battery that is charged by a small solar panel. The spikes are a deterrent to birds that can foul the rain gauge.
On a 30′ mast, near the instrument package, are a wind vane and anemometer.
Data are transmitted to my indoor displays. One of my displays has a data logger with a wired connection to an internet router.
With software, supplied by Davis, my data is downloaded to a PC for storage and analysis. My data are also uploaded to Davis WeatherLink, Weather Underground and The Citizen Weather Observer Program.
My secondary instrument cluster is a BloomSky package. On the left is a solar-powered barometer, thermometer, hygrometer and UV sensor package. It also has a fisheye WiFi camera. On the right are a solar-powered anemometer, wind vane and tipping bucket rain gauge. Data are sent to my router via WiFi and uploaded to BloomSky.
Data are displayed via The BloomSky App as shown.
