The PrintAirPipe – AirFlowSensor Segment can be used to measure the airflow or air velocity in the pipe system.
The electronics are based on an ESP32 S3, three LEDs, and a Hall sensor. The entire electronics can be powered via a USB-C cable. The rotation speed of the propeller inside is displayed externally using an animation. (More information in the video linked below)
