This is the second version of an appliance controller for a hydroponics system. This version actually has a user interface with 3 different modes: Time of day, Day of Week (2 triggers per day), and Temperature mode. Also uses the ATmega328P-PU. Meant to be able to control many different types of appliances in a hydroponics system like lights, pumps, etc.

This device has a waterproof temperature probe connected to an ATmega 328P-PU (same IC used in Arduino Uno), an LCD screen and a relay. Used to trigger heating or cooling units for a reservoir of a hydroponics garden system. This is the first version of my Plant Keeper and does not have a User interface for programming the parameters.
