I haven't been doing a very good job of keeping this site up to date, but have been working hard on the flow sensor.

At this time I've seen a lot of interest from people who are designing ventilators and would like to use this sensor as a component in their designs.  That's great, it's the reason I first started the project!

I've shifted focus from making a stand alone monitoring device to making a simple accurate sensor that can be easily integrated into other projects.  I'm still planning to pursue the stand alone version as well, but that's a secondary task at the moment.

I'm currently in the process of evaluating different pressure sensors.  The ones I'm using now are great, but I have concerns about their availability, there isn't much stock out there and what is there seems to be going quickly.  I've got a few different boards being built right now which will allow me to test with a couple different models of pressure sensors which are both inexpensive and abundant.  Stay tuned...
