The Sparkfun Anemometer is a precise tool designed to measure wind speed efficiently. As the wind propels the cups, they rotate an enclosed magnet, which triggers a reed switch with each rotation. This action can be monitored via the two inner conductors of the RJ11 connector, using a digital counter or interrupt pins on your microcontroller. The conversion rate for wind speed measurement is 2.4 km/h per switch closure per second.Ideal for weather enthusiasts and hobbyists, this anemometer offers a straightforward method to monitor wind conditions. Whether you're integrating it into a homemade weather station or using it for educational projects, it provides accurate and reliable data.One of the standout features is its compatibility with the Weather Meter Kit, allowing for seamless integration into larger weather monitoring systems. Its straightforward design makes it a perfect choice for both beginners and experienced users looking to explore meteorological phenomena.Compact and easy to set up, this device is a practical addition to any project requiring wind speed measurements. With its robust construction, it ensures durability and consistent performance in various weather conditions.
