Hello Everyone,
I am consisdering building an electronic weather station which will basically consist of two main blocks, one of which will contain all of the nessesery instruments and can be be placed in a remote location, this will then radio back data to another block attached to a PC where the nesserery software will display various readings.
At the moment I am just doing my reaearch and am finding it difficult to come across simple circuits or IC's which will act as as a tranducer in sensing different aspect of the weather. So far I've come across temperature semsors quite cheap and humidity sensors. Everything else seems quite expensive. I would like at least 4 different aspects, maybe temperature, windspeed, atmospheric pressure, rainfall.
My main question is does anybody know of any circuits or IC's (or resonanbly cheap anemomemeters) which would carry out the above tasks. I am not really looking for excessive accuracy and I don't think I would be willing to pay much more than 10Euro for an IC (but maybe I may have to). Also are there resonably priced temp sensors which will also calculate negative temps?
If anyone has ever tried this type of project before please let me know and if anyone knows of any sites or nice circuits plaese let me know.
Thanks very much for your time
Kev
