anemometer

Anemometer data logger prototype on porch

We are using a Vortex wind sensor. One revolution per second equals 2.5 mph. Since our anemometer has a relay (a mechanical switch), it creates a switch bounce. Therefore, we need a debounce circuit.

Opportunities to improve the system

• We are currently supplying power to the Arduinos via USB. If we used DC converters from the batteries to the Arduinos, we might save some electricity.
