Purpose and Scope

Our system provides the implementation of two different sub-systems and can interface with the user through an on-line calendar and a mobile push-messages service. The first sub-system is composed by food and water automatic dispensers. Food is contained in a tube, which has sensors able to notice the amount of food and thanks to these sensors, the system sends a notification to the user. A mechanic actuator (an engine and a valve) manages the food dispensing. The user through the on-line calendar can schedule day-by-day time slots allowing the system to dispense food. A sensor under the food bowl allows the system to send a message to the pet's owner to control if the pet cosumed food. Water dispenser is a container, placed on the ground, with a pomp inside bringing water to the bowl. The water bowl has some sensors and the water pomp provides to fill the bowl when the water bowl is empting . The second sub-system is composed by a sensor placed under the pet's bed recognizing if the pet stay too long in the bed and activates a toy moving automatically and the pet can play.
