Example Code for Arduino-Air Velocity Reading

Hardware Preparation

• DFRduino UNO+IO Expansion Shield (SKU:DFR0216-2) ×1
• Gravity: PAV3015 Air Velocity Sensor（SKU:SEN0639）×1
• Gravity 4Pin I2C cable (Comes with Gravity: PAV3015 Air Velocity Sensor)

Software Preparation

• Download Arduino IDE： Click to download Arduino IDE
• Download DFRobot_PAV3000 library：DFRobot PAV3000 Github
• Arduino IDE V2.0.0 (or above) can search

Wiring Diagram

Other Preparation Work

1. Install the DFRobot_PAV3000 library into the Arduino IDE (follow Arduino IDE library installation guidelines).
2. Ensure the sensor is connected correctly via the Gravity 4Pin I2C cable.
