Hello everyone!
I have a weather meters(http://www.sparkfun.com/datasheets/S...0Assembly..pdf) from sparkfun electronics, I read its manual but not all are really clear for me. But here is what I understand so far.
Sensor:
RAIN GUAGE - I think it's similar to a switch button, so I just need to count how many times it has been switched...am I right?
WIND VANE - I also thinking I can use ADC in reading the value from the sensor.
ANEMOMETER - don't really know how to on this one.

Planning to use Pic18F4550 at 20Hz.
I hope anybody can help me out on this one.

Thanks in advance,
