Product Description
The DFRobot Gravity: PAV3015 air velocity sensor module SEN0639 is a compact digital anemometer for airflow monitoring in embedded electronics and control systems. It is based on the Posifa PAV3015D sensing element and uses a thermal measurement principle in which temperature differences across a thermopile structure are evaluated to determine air velocity. This approach avoids mechanically moving parts.
With a measurement range of 0 to 15 m/s, an accuracy of ±5% F.S, and a typical response time of 125 ms, the module is suitable for continuous airflow monitoring in compact systems. The Gravity I2C interface simplifies integration with microcontroller platforms and control hardware. A supply range of 3.3 to 5 V supports use in a wide range of embedded designs.
The compact solid-state construction makes the module suitable where conventional mechanical anemometers are impractical due to size, wear, or installation constraints. The sensor module can be integrated into electronic equipment, ventilation systems, mobile instrumentation, and closed-loop control applications that require reliable real-time airflow data.
