Design and Code for a cheap blower for inflating a double poly roof for a greenhouse.
Goals:
- cheap
- runs on 12V DC
Stages: #1 - timing based control #2 - pressure based control

This project combines the following:
- 12V Blower - e.g. http://www.seaflo.us/product/3-line-bilge-blower-fan/
- http://digistump.com/products/1 ( or any other arduino )
- MOSFET Driver board ( e.g. https://www.pollin.de/shop/downloads/D810329B.PDF )
- BMP180 pressure sensor ( in eval if this one is sufficient )
- greenhouse-flange ( e.g. http://shop.exner-gruenetechnik.de/Gewaechshaustechnik/Zubehoer-fuer-Gewaechshaus/Anschlussflansch--Einblasventil-mit-Anschluss-fuer-Drucksteuerung.html )
- flex-tube e.g. ( http://shop.exner-gruenetechnik.de/Gewaechshaustechnik/Zubehoer-fuer-Gewaechshaus/Luft-Schlauch---flexibel------60-mm---mit-2-Klemmen.html )
