SparkFun Air Velocity Sensor Breakout - FS3000-1005 (Qwiic)

by Sparkfun

Need to keep track of the airflow in your data center or around your servers?

How about making sure your HVAC and air control systems are functioning at full capacity? Or, if you're more fun, what about figuring out how fast your RC airplane is going? Well, the new SparkFun FS3000 Air Velocity Sensor Breakout can help you with all that and more! It's super easy, super quick (Qwiic!) to hook up, and super fun to play with.

This breakout board is focused around Renesas' FS3000, a surface-mount air velocity module utilizing a MEMS thermopile-based sensor. It features a digital output with 12-bit resolution and comprises a โ€œsolidโ€ thermal isolation technology and silicon carbide coating to protect it from abrasive wear and water condensation.

SparkFun have written an Arduino library to help you get started quickly. You can download the library through the Arduino library manager by searching 'SparkFun Air Velocity' or you can get the GitHub repo as a .zip file and install the library from there.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you canโ€™t hook it up wrong.
