Raspberry Pi greenhouse with climate monitoring and controls. pi-house is an indoor greenhouse with the intention of bringing a reliable, relatively self sustaining personal garden. There will, in the future, be an outdoor version as well.

The greenhouse itself is mostly sealed with multiple values for environmental conditions in the greenhouse being measured at all times. The monitoring systems include a soil moisture and temperature sensor as well as an ambient temperature sensor. A light sensor will monitor if a secondary light source is necessary (if there is a cloudy day or other weather conditions that may limit sunlight).

• Two motors control a set of vents, letting in outside air to be blown across the plants and out.
  • Screens cover the vents so solid objects cannot freely enter the greenhouse.
  • Internal fans circulate the air inside as long as the temperature is warm enough.
  • Heat lamps will be activated if the temperature is too low.
• Mist watering system with a pump and tubing that goes across the top of the greenhouse.
  • A water tank will need to have sufficient water for the misting system to be functional. If there is insufficient water the pump will not run.
  • Opposite the vent on the top of the greenhouse, there is a manual opening for watering the plants inside.
