[Ken_S] sent in his GardenMon (coral cache) project. It’s a set of light, humidity, moisture and temperature probes that monitor the surface and below ground conditions in his garden. He’s using several picaxe micro controllers to take readings with a variety of off the shelf and commercial sensors. Once he started collecting the data, he added a programmable servo controlled watering valve with a configuration that he tweaks accordingly.
The site is on geocities, so use the cache.

I had a few requests, and this fits, so I added a home hacks category.
