Board-Mount Airflow Sensors for Electronic Systems

May 3, 2022 | Posted By: Degree Controls Inc.

Designing airflow intelligence into electronic systems with board-mount air velocity sensors helps protect components from thermal damage and ensures the overall efficacy of air flow products such as air cleaners and purifiers1. Incorporating Degree Controls board-mount air velocity and temperature sensors onto pcbas in electronic enclosures allows engineers to collect performance data and enables systems to adapt in response to changing conditions.

Board-Mount Airflow Sensors for Electronic Systems
F661/F663 Horizontal Profile and F660/F662 Vertical Profile

F66x board-mount sensors measure air velocity and temperature at strategic locations within electronic assemblies and enclosures. They are used to:

  • Determine normal airflow levels
  • Detect a loss of airflow due to a hardware issue such as fan failure, clogged filter, or inlet/outlet obstruction
  • Increase fan speed to maintain safe operating temperatures and remove heat generated by electronic components
  • Adjust fan speed to deliver enough UV dosage for effective air treatment

F66x pcb-mount, digital airflow sensors measure air velocity and air temperature simultaneously. Sensors are available in either horizontal or vertical profile packages to accommodate applications where component height is restricted, or board space is at a premium and the smallest possible sensor footprint is needed. For easy integration, F66x board-mount sensors may be installed in a socket or soldered directly to a printed circuit board. Choice of supply voltage is available, and sensors use digital I2C or UART output to communicate airflow information to a control device. Built-in temperature compensation assures the correct values are automatically reported.

1CADR, the clean air delivery rate, is a standard for evaluating the effectiveness of air purification devices.  It is cubic feet per minute of air that has had all particles of a given size distribution removed and is affected by air flow and filter efficiency.
