Auto-Window Project

Tags:
Category: Misc
Progress: In Progress
Cost: About 200 bucks
Time to Build: 8 months

This is a system I developed to close automatically a home window when it detect rain. But I extended it to remote manual controls and more sensors with logic. I plan another different sensors to install on it, but on this first prototype I just used Rain and Temperature.

The mini prototype cost about 20 bucks and 1 week of hard work. The real size one cost about 200 bucks and 8 months of lots trouble obtaining the pieces. For now, it just need to be installed in a real window.

hahaha thank you! I'm new on it

at least, I didn't use any microcontroller on this 2 prototypes. I was restricted  to use only what they teach at school [this project is also for school grades xD] so the logic I used was based on TTL technology. Futurely I want to build one using microcontrollers and a HMI that makes the client choose some logic options or enable/disable sensors virtually. What do you think?

Good stuff! Back in high

Good stuff!

Back in high school (yikes...'93 or so?) we built a system like this for a "Photovoltaics Fair" -- basically the same idea you have, except also powered by solar cells.  Our idea was that it should be a window for an attic or upstairs window, to help with attic venting on hot days, etc.

Back at that time, we didn't have the variety of micro-controllers now available, so everything was done with old-fashioned logic -- comparators, relays, etc.  It was a nightmare to get the settings right (we based the open/close decision on the "rain" sensor as well as "internal" and "external" temperature sensors and light level).  Would be fun to do something like this again!
