  • 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.
