SEN0639

SEN0639 is a Gravity: PAV3015 air velocity sensor (0-15m/s, I2C). This is a compact digital anemometer designed for accurate airflow monitoring in embedded electronics and intelligent control systems. Built around the Posifa PAV3015D thermal sensing element, this airflow measurement module calculates wind speed by detecting temperature differences across a thermopile structure. The solid‑state sensing approach eliminates mechanical moving parts, improving reliability and durability compared with traditional cup-style instruments. With a measurement range of 0–15m/s, ±5% F.S accuracy, and a fast 125ms response time, this compact wind speed sensing board enables dependable real‑time airflow monitoring for server cooling systems, HVAC optimization, and UAV airspeed detection.
