DFRobot Gravity PAV3015 Air Velocity Sensor
DFRobot Gravity PAV3015 Air Velocity Sensor operates on the thermopile principle to measure airflow from 0m/s to 15m/s with ±5% F.S accuracy. This air velocity sensor is a compact, high-performance anemometer for precise airflow measurement, based on the Posifa PAV3015D sensor. The Gravity PAV3015 air velocity sensor uses a solid-state method that provides significant advantages over traditional cup anemometers. This air velocity sensor features low 10mA power consumption, a 3.3V to 5V Gravity I2C interface, and an exceptionally fast 125ms response time. The Gravity PAV3015 air velocity sensor is ideal for embedded systems in applications like server cooling, HVAC monitoring, and UAV airspeed detection.
The Gravity PAV3015 air velocity sensor offers a minimal footprint, enabling seamless integration into compact devices, embedded systems, and portable equipment with limited space. This enables airflow measurement in applications previously limited by sensor size.
