I have built my second unit without the Baro Sensor as I now believe it to be an unnecessary complication.
Using cockpit static the baro sensor will be variable in an airborne aircraft and in reality the GPS altitude is accurate enough for collision avoidance purposes. Any altitude difference of less than 1000 feet will certainly require horizontal action to deconflict.

I do have the Hobby Electronics sensor in my first unit and it is surprising how accurate it is, but it is avoidance of conflict which is the aim rather than accurate detection of altitude variation from transponding aircraft.

Have a look at this to see what is on offer in the USA to replace an old transponder.

Simple answer is no, more detailed answer can be found on previous threads.
However FR24 does a very good job of picking up Flarm and I have been wondering about an integration.
