Hi Scott,
Any chance of a circuit posted somewhere? Even if it is just a photograph of a drawing on the back of a napkin :) I have access to a small number of old wx stn sensors (WM918) mostly anemometers and rain gauges. (Work used to sell them) The wind direction part is interesting as to has a 10kohm, 360 degree pot so you get an analogue voltage out dependent on wind direction. The rain gauge & wind speed bits are a simple reed switch \ magnet arrangement. Rain gauge reads about 1mm of rain per 'pulse' and the anemometer seems to be about 4 pulses/sec for 10mph, although it seems to have a slightly non-linear curve to it. (See <http://www.qsl.net/zl1vfo/wx200/wx_index.htm> & look for Anemometer near the bottom left.) Anyway, how closely do these characteristics match the sensors that you are using, or could the firmware allow for 'calibration' / 'scaling' of inputs in the future so things read reasonably correctly? As an aside, watch out for Hams running a kilowatt or so of HF near the sensors - the leads can pick up lots of induced voltage as you might guess & you really need heavy duty low pass filtering to keep that lot from reaching the uP inputs & screwing with the readings. (Nearby lightning flashes can play havoc too...) Anyway, hopefully the sensors I have access to are compatible, or can be made to be. -Ian ZL1VFO --- In [email protected], Scott Miller <sc...@...> wrote: > > It's taken longer than expected due to component shortages, but I've got > half a dozen ADS-WS1 weather stations assembled and nearly ready to ship. > > https://www.argentdata.com/catalog/product_info.php?products_id=135 > > There's a ton of stuff not done yet, but the prototype in my office has > been working well for weeks with Virtual Weather Station. ~ snip ~ > Scott
