![]() I sawed a single slit, about an inch long, in the end of the tube. (But at least I'll have measured the wind speed at which it collapses!)įitting the alternative mast was quite simple. The tube is meant for use as a wardrobe rail - it's a bit thin walled for this application, and I suspect it may not survive a high wind. Inspired by Grant's efforts, I went to B&Q and bought a 6' long 19mm tube to make a taller mast, in the hope of getting more realistic wind measurements. You can read more about his installation on his blog. Soon after putting this page on my web site I received an email from Grant Gibson, who'd found this page whilst looking for info on the version he'd just bought. These weather stations, in their various brands, are obviously becoming popular. Even after doing this I don't hold out much hope of truly accurate readings. I need to make some sort of shield for it, perhaps from a length of plastic pipe. Despite having a white louvred enclosure this is badly affected by strong sunlight, over-reading by 5 centigrade degrees or more. Last of all is the temperature & humidity sensor, which also contains the radio transmitter. ![]() ![]() These are far too near the ground (and other obstructions) to give meaningful measurements, but I should at least be able to judge relative wind speed from day to day. ![]() At the top are the wind speed and direction sensors. The first two pictures show my first installation of the weather station's outdoor sensors, mounted on my garden fence with a TV aerial standoff bracket. My station came with some Windows software called EasyWeather, but I've connected it to an embedded Linux box (an Asus WL-500gP V1 router) so I can upload "live" weather data to this web site. One thing that sets these apart from other weather stations is that they have a USB socket to connect to a computer. It's branded "Elecsa AstroTouch 6975", but a brief web search showed that it's functionally identical to several other brands, such as Watson W-8681 or WH-1080PC / WH1080 (the WH1081 is similar, but doesn't have a radio controlled clock). In April 2008 I bought an electronic weather station. ![]()
