Portable greenhouse automatically regulates temperature for optimal conditions

Eco Factor: Automated greenhouse maintains ideal growing conditions.

Eco-conscious DIYer Brian Merritt has created a portable greenhouse and a seed starter that includes high-tech features to regulate interior temperature of the greenhouse. A standard greenhouse gets too hot if kept closed and gets too cool if opened, but this high-tech alternative makes use of several built-in sensors to do the job in a better way.

The user has to select a temperature between 60 and 95 degrees Fahrenheit, by 5 degree increments. Once the temperature is selected, the built-in sensors and microcontroller automatically adjust the vent opening to help maintain that temperature. The sensors and microcontroller are based on an ultra low power design, enabling the system to run all day for a month on just four AA batteries.

The design includes a low-battery warning indicator, a daylight sensor and a bank of high-intensity LEDs that provide nighttime illumination for inspection purposes.
