A hotwire anemometer is a precise instrument for measuring tiny wind speeds, particularly in environments where detecting minute airflow changes is crucial. Here's an introduction to using a hotwire anemometer for this purpose:
Overview of Hotwire Anemometers
A hotwire anemometer consists of a thin wire, usually made of platinum or tungsten, which is electrically heated. As air flows over the wire, it cools down. The cooling rate is proportional to the airspeed, allowing the device to measure the airflow's velocity accurately.
