AWM5101VN Air Flow Sensor For Medical Devices Industrial Process Control Consumer Electronics

The AWM5101VN belongs to AWM5100 series, featuring a microbridge MEMS sensing element that detects mass flow directly without temperature or pressure compensation. It is optimized for clean, dry gases (air or non-corrosive gases) and delivers a linear analog output proportional to flow rate. With its compact surface-mount package and low power consumption, it is widely used in medical devices, HVAC systems, and industrial process control where space and energy efficiency are critical.

Key Features:

• Direct Mass Flow Measurement: Eliminates the need for additional temperature/pressure compensation, simplifying system design and improving measurement accuracy.
• Linear Analog Output: 0.5 V – 4.5 V signal range (0 flow = 2.5 V, bidirectional flow = ±2 V deviation) for easy integration with microcontrollers.
• Compact & Low Power: SMD package saves PCB space; low power consumption (typ. 60 mW) suits battery-powered devices.
• Bidirectional Flow Detection: Supports both forward and reverse flow measurement, expanding application flexibility.
• Robust MEMS Design: Honeywell’s microbridge technology ensures long-term stability and resistance to mechanical stress.

Typical Applications:

• Medical devices: Respirators, nebulizers, oxygen concentrators, and CPAP devices.
• HVAC & building automation: Air flow monitoring in ventilation systems and air purifiers.
• Industrial process control: Low-flow gas metering in precision manufacturing and analytical instruments.
• Consumer electronics: Gas flow detection in fuel cells and miniaturized air quality monitors.
• Automotive: Cabin air flow sensing (specialized variants) and emissions monitoring modules.
