# Arduino Greenhouse Shield More to come! ## Artifacts Bdale's [presentation](GreenhouseShield.odp) from the Arduino Miniconf at LCA 2011 in Brisbane. A schematic for this circuit can be found in the the [hw/greenhouse](http://git.gag.com/?p=hw/greenhouse;a=summary) repository at [git.gag.com](http://git.gag.com). ## Status The system was finally put online on 7 April 2013, controlling a 750 watt heater and through-wall fan with automatic louvers. The temperature thresholds are set to 7 and 32 C, below which the heater is on and above which the fan is on. ## Future Plans We're not using the 128k EEPROM part any more. Instead, the plan is to add a [TeleShield](http://altusmetrum.org/TeleShield/) board to the stack which gives us a micro SD card for massive data storage, and an [Altus Metrum](http://altusmetrum.org) standard UHF radio link that will make it possible to check on the status of the greenhouse from the main house.
