Gravity: PAV3015 Air Velocity Sensor (0-15 m/s)

Gravity PAV3015 Air Velocity Sensor, based on Posifa PAV3015D chip, uses thermopile principle—heated metal wire, measures its side temperatures to calculate air velocity. Smaller than traditional cup anemometers, it suits server air duct monitoring, pipeline airflow detection, and maker projects (drone airspeed, bicycle wind speed). Featuring standard Gravity I2C (plug-and-play) and 3.3–5V power, it integrates easily with Arduino, ESP32, Raspberry Pi.
