Description

The DFRobot Gravity PAV3015 Air Velocity Sensor employs a thermopile-based sensing principle to detect airflow without mechanical components, ensuring long-term stability and resistance to dust and contamination. It outputs a calibrated digital signal via its I2C interface, providing direct velocity readings in meters per second.

Designed for embedded and industrial monitoring, the sensor operates across a wide temperature range of -25°C to +85°C and 0-100% RH (non-condensing). Its compact, durable construction is suited for integration into HVAC systems, environmental stations, and drone anemometry applications where precise, real-time airflow data is critical.

Key Features

  • Solid-state thermopile airflow sensor with no wear-out mechanisms
  • High-accuracy measurement with ±5% full-scale precision across 0-15 m/s
  • Rapid dynamic response with a typical update rate of 125 milliseconds
  • Optimized low-power design, drawing only ~10 mA for battery-operated setups
  • Wide operating voltage range (3.3V to 5V DC) for flexible system integration
  • Gravity-standard 4-pin I2C interface for simplified wiring and prototyping
  • Robust environmental specification: -25°C to +85°C, 0-100% RH
  • Compact PCB footprint (35mm x 22mm) for space-constrained installations

Applications

  • HVAC system airflow balancing and duct velocity monitoring
  • Environmental weather stations for wind speed measurement
  • Drone and UAV anemometry for flight stability and data logging

Frequently Asked Questions

What is the operating voltage range for the PAV3015 sensor?

The PAV3015 operates from a 3.3V to 5V DC power supply, making it directly compatible with most microcontrollers like Arduino, ESP32, and Raspberry Pi without requiring a level shifter. It draws a low operating current of approximately 10 mA.

How do I connect and read data from the PAV3015's I2C interface?

Connect the sensor using the included 4-pin Gravity cable to your MCU's I2C pins (SDA, SCL, VCC, GND). DFRobot provides open-source Arduino libraries that handle communication, returning calibrated air velocity values in meters per second directly over the I2C bus.

What is the sensor's response time and accuracy?

The sensor has a fast typical response time of 125 milliseconds, suitable for real-time monitoring. Its accuracy is ±5% of the full-scale range (0-15 m/s), providing reliable measurements for HVAC control, environmental sensing, and process automation applications.

Can this sensor be used outdoors or in harsh environments?

Yes, the solid-state thermopile design has no moving parts and is rated for operation from -25°C to +85°C and 0-100% relative humidity (non-condensing). For permanent outdoor installation, consider a protective enclosure to shield the PCB from direct water ingress.
