Honeywell Technologies HAF Series Digital Airflow Sensor for Air, 0L/min Min, 0.1L/min Max

This Airflow sensor measures minute Airflows for monitoring and control in sensitive systems. It operates from sub-ambient to moderately elevated temperatures and is built to detect Air movement at very low rates. The device outputs digital data and is intended for integration where compact, low-flow measurement is required, particularly where polymer housings and low-voltage operation are preferable.

• Digital output enables direct interfacing with microcontrollers
• Operates down to 0 L/min allowing detection of zero-flow conditions
• Handles up to 25 psi enabling use in moderate-pressure environments
• Compatible with 5 V supply simplifying system power design
• Polymer housing reduces device mass and resists corrosion

• Suitable for monitoring respiratory or medical gas delivery systems
• Ideal for precise control in Compact HVAC components
• Used with microcontroller systems for low-flow diagnostics
• Can be used for leak detection in pneumatic assemblies
• Used for environmental sensing in laboratory instrumentation

It is designed specifically to monitor air.

It operates between -20 °C and 70 °C.

The enclosure is polymer, which provides a lightweight, non-metallic option suited to corrosion-sensitive installations.

It is a digital device, providing discrete electrical output for processing.
