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