Air Velocity Sensors with Digital I2C Output

Posifa Technologies’s new PAV3000 series of economical, high-performance air velocity sensors with digital I2C output and a surface-mount footprint for thermal management and filter monitoring in even the most space-constrained locations.

Unlike thermistor-based solutions, the PAV3000 has a MEMS sensor core that is minimally affected by ambient temperature changes and which provides instant real-time feedback on proper air flow at critical locations.

PAV3000 helps identify areas that require unusually high air flow to maintain stable temperatures, layouts for rack enclosures with air cooling — such as those found in data centers — can be modified to reduce cooling demands for increased energy savings.

In applications such as HVAC systems, air velocity measurements can be used to determine when filters need to be replaced. This ensures hardware is adequately protected during heavy use, and it allows customers with light usage requirements to benefit from extended change intervals.

Measuring air velocity at 7 m/s (PAV3005V) and 15 m/s (PAV3015V), the PAV3000 series devices offer extremely fast response times of 125 ms typical in a compact, robust package. The air velocity sensors feature a 12-bit digital output, 3.3 V supply voltage, and supply current of 13 mA.
