This doesn't need to tie into anything. I just need a good, cheap way to monitor duct temperatures before and after my furnace, and possibly airflow. Is 1-wire probably my best bet?
I think there are some 1-wire static pressure sensors that I can use for this. Any recommendations on brands/places to purchase?
I am "tuning" my HVAC system. The builder installed the HRV and made the runs for it 60-80 feet long, which is a huge no-no. It's rated for 200cfm, but according to the manufacturer, I'm probably getting under 50cfm. Also, the room furthest from the furnace is not getting enough airflow. I've played with dampers and done a bunch of things, but I have no way to actually measure what is going on. I'd like to increase my fan speed, but I need to measure the current temperature increase to make sure I don't increase it beyond what it should be and end up with lukewarm air coming out of my ducts.
Also, I want to be able to measure the pressure in the basement, versus the pressure outside, and ensure that I have positive pressure in the basement to help with radon abatement.
