Sparkfun Air Velocity Sensor only reading max air flow rate, even when blocked

Hi there, I am trying to use SparkFun Air Velocity Sensor Qwiic Kit - FS3000-1015, but when connected through the Qwiic, it is only reading the max air flow rate (15m/s) even when the air flow is blocked.

There’s a note for boards that use the Apollo core (which the Artemis does); are you set to 400KHz? Air Velocity Sensor Breakout - FS3000 Hookup Guide - SparkFun Learn (search for ‘apollo’ in the page to see the note)

Do you have another i2c device you can test?

I have downloaded the Apollo 2.1.0 library instead as that was mentioned to also work. Unfortunately I do not have another i2C device to test out at the moment.

Alrighty - do you happen to have a different microcontroller?

I happen to have a teensy 4.0

Try hooking it up to the teensy and if the readings are also maxed out it is likely defective

Unfortunately there seems to be some unknown issue with the i2c communication on the other microcontroller, is there another way to test it using the components in the kit or any other common issues?

Additionally, I have also noticed that the raw data is transmitting a value of 3723 which is higher than the sensors range of 409-3686

Update: today the board is not even connecting to the Artemis Nano Board through the Qwiic connection

Was it purchased from us? If so head over to Returns (contact vendor if purchased elsewhere) and we’ll get ya squared away
