Abstract: A composting apparatus comprises a bin, an access panel, an aerator, a water content sensor, a valve, and a composting controller. The bin stores organic materials and compost therein. The access panel, disposed over an opening within the bin, allows access to an interior of the bin. The aerator, disposed within the bin, allows air into the bin to aerate the organic materials and compost therein. The water content sensor, disposed within the bin, senses a quantity of water within the organic materials and compost within the bin. The valve, coupled to a water line, controls a quantity of water added to the bin. The composting controller, coupled to the water content sensor and the water valve, actuates the water valve to control a quantity of water added to the bin based on the sensed quantity of water within the organic materials and compost.
