case for the EC fan 24V 55W each at max. speed, diam 175mm bought from china ~40$
the box have the bypass channel included on the right side, the dumper is not fitted yet.
end the finished product without the controller
next to do:
- air filters
- controller - speed controll with ballace, flow sensor on exhaust and inlet air, and other feature.
- bypass dumper (maybe with 9g servo or a simple dc motor for on-off shuting
The controller will be one Arduino connected to internet for using Blynk app on my phone, very easy to use.
The sensors will be DS18B20 and for humidity sensing DHT22.
