## Description

This compact digital anemometer measures air velocity for embedded electronics and intelligent control systems. It is built around the Posifa PAV3015D thermal sensing element, using temperature differences across a thermopile structure to calculate airflow without mechanical moving parts.The board covers a 0–15 m/s measurement range with ±5% F.S accuracy and a 125 ms response time, making it useful for real-time airflow monitoring in cooling, HVAC, environmental sensing and UAV applications.DFRobot’s Gravity I2C interface keeps wiring simple, and the 3.3V–5V supply range suits common controllers including Arduino, ESP32 and Raspberry Pi. The package includes the Gravity: PAV3015 Air Velocity Sensor and a Gravity 4-pin sensor cable.Features:Solid-state thermal airflow sensing technology without moving mechanical partsWide air velocity measurement range: 0–15 m/sHigh measurement accuracy of ±5% F.SFast response time of 125 ms for real-time airflow monitoringGravity I2C interface for simplified wiring and integrationCompatible with Arduino, ESP32, and Raspberry Pi controllersLow operating current of only 10 mACompact structure suitable for embedded systems and portable devicesSpecifications:Supply Voltage: 3.3–5VOperating Temperature: -25 to +85 ℃Operating Humidity: 0–100% R.H. (non-condensing)Operating Current: 10 mAResponse Time: 125 msMeasurement Range: 0–15 m/sAccuracy: ±5% F.SSuitable for data centre cooling checks, smart HVAC airflow measurement, drone airspeed detection, portable environmental instruments and battery-powered airflow devices.

**Product Type:** Air Velocity Sensor
