I've been promising a weather station kit for a long time, but I've just about given up on making it a do-it-yourself kit. There are only so many through-hole sensors available (that don't cost an arm and a leg) and getting the required resolution out of an analog baro sensor means adding more parts than I want to squeeze into the enclosure I've got in mind.
Making it all surface mount means I can use a much cheaper barometric pressure sensor with accuracy as good as or better than the through-hole one, lower power consumption, and a lower part count. It also provides high accuracy temperature measurement with no additional parts. Anyway, I just wanted to see if anyone has specific feature requests for the new board. I'm hoping to have the first board design sent off by the end of the week. The idea is to have both a serial output that could drive an external TNC, and also a direct radio connection. Granted, hooking it up to a radio and also having it in a location where it'll get good temperature and humidity readings could be a problem. Here are some specs so far: Wind direction Wind speed Rain gauge (~1/100 inch resolution) Temperature (~0.5C absolute accuracy) Pressure (~3 hPa absolute accuracy, 0.2 hPa relative) Humidity (3% RH, optional add-on for about $20) I'm estimating a retail price of about $130 with humidity, $110 without.
