The controls for the germination chamber utilizing Mysensors and Arduino on a radio network. The plastic box has the controller and the moisture/heat sensor. The white outlets are standard 433MHz remote control outlets connected to the home automation controllers. The light will be on a timer and heat mat will be controlled by temperature
These are several controllers some homemade and others off the shelf. All of them will utilize Arduino system programs. The lower left is a wifi relay board which will control 24VAC solenoid valves for watering. The middle 6, the home made will monitor temperature and soil moisture when complete. The others are for show but will be put to use.
