SparkFun Weather Meter Kit
Measures wind speed, wind direction, and rainfall
Includes Wind Vane, Cup Anemometer and Tipping Bucket Rain Gauge
The SparkFun Weather Meter Kit represents the three core components of weather measurement: wind speed, wind direction, and rainfall.
None of the sensors in this kit contain active electronics, instead, they use sealed magnetic reed switches and magnets so you'll need to source a voltage to take any measurements. The positive side of this is that the sensors easy to interpret. The rain gauge is a self-emptying bucket-type rain gauge which activates a momentary button closure for each 0.011" of rain that are collected.
The anemometer (wind speed meter) encodes the wind speed by simply closing a switch which each rotation. A wind speed of 1.492 MPH produces a switch closure once per second. Finally, the wind vane reports wind direction as a voltage which is produced by the combination of resistors inside the sensor.
All of the included sensors are supplied with RJ11 terminated cables, for information on the pin-out of the cable, check out the datasheet.
