Weather Meters
Whether you’re an agriculturalist, a professional meteorologist or a weather hobbyist, building your own weather station can be a really rewarding project. When you’re measuring weather, however, you need some pretty specialized sensors. This 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 are easy to interpret: ..
