Typically, air flow is measured with a hot-wire anemometer. Here's an alternative version of that concept using two thin-film platinum resistance temperature detectors. A high-performance mixed-signal ...

Anemometers simply measure wind speed. Many designs use the wind to spin a fan or other mechanical device. Anemometers simply measure wind speed. Many designs use the wind to spin a fan or other ...

Anemometers are an important category of environmental sensor. Articles about their design, data capture, and linearization have comprised topics featured in EDN Design Ideas, several quite recently.

A recent Design Idea presents a circuit to measure an airflow rate up to 2000 fpm using two transistors in a Darlington configuration. One transistor works as a self-heated thermal sensor and the ...

Students of Ho Ming Primary School and Pok Oi Hospital 80th Anniversary Tang Ying Hei College have won an anemometer design competition organised by the Hong Kong Observatory and the University of ...
