<![CDATA[New module - SDP3x differential pressure sensor.]]>Would love to be able to use the M5Stack infrastructure to create a monitor for my HVAC filters to alert when it is time to change filters.

Do you plan on programming in Arduino IDE or UIFlow (Python)? The sensor is i2c using qwiic cables and would be easy to program in Arduino, but quite a task to do in UIFlow or Python.

Have not looked much beyond that do to time constraints. I have ordered an SDP3x breakout from sparkfun, hoping to do some additional research soon.

Hello.
What have you researched so far in order to connect to your HVAC?
