LazyPlants v2

arduino

1. Controls lights on a timer. 2. Tells you when a plant isnt getting enough water from drip system. 3. Records temp and humidity to confirm fruiting temp for peppers more to come wifi monitoring of arduino with raspberry pi & web interface PoE power and data transmission from soil sensors through home ethernet wiring mulyiplexed through 8 twisted pairs of cat5e more lights & hydroponics!
