I've just bought one of these, can anyone tell me how they work please

[boxtops]

Are there no instructions with it? !

[bibblebub]

On that page is a link for the manual http://www.oregonscie.../BA900_M_EU_final.pdf

Yes but it doesn't explain 'how' it works .

[Spreeny]

Yes but I mean 'how' does it work i.e does it contain a hygometer or hydrometer or
something ........ how does 'it' know which symbol to 'light up'

[rojash]

Presumably it works the same way as any other electronic weather station - a temperature sensor and a barometric pressure sensor. As far as I can tell, the only difference is in the way that it displays the result.

[heathfield]

The weather station contains a transistor that is 'pressure sensitive'. In weather forecasting it is the changes in atmospheric pressure over time (trend) that give an indication of what's likely to happen. The weather station measures these changes and displays the (possible) weather prognosis. The results are always a generalisation, since there are other factors involved that the weather station can't take into account. Scroll down to ''General Rules...'' here, to see how pressure changes affect the weather...
