Showing off my greenhouse that has automatically opening and closing windows. Powered by old car battery, driven by old cordless drill and controlled by barebones Arduino. If inside gets too hot or not so hot but too moist it opens the windows. If weather is stormy and dangerous for open windows, they get closed – that’s why the anemometer is there. It also logs temperature measurements on SD card.
This thing was in testing few days this autumn, will have to wait til next summer to see how much difference it makes for tomato plants. It also needs some covers to keep the mechanical parts from rain.
