| # Outdoor Smart Dog Feeder ## Introduction An automatic dog feeder relieves a dog parent of the habitual task of refilling their pets' bowls. Due to work and travel, it can sometimes prove to be difficult to keep track of and complete this task on a regular schedule. A simple solution of a self feeder is not a viable action because most dogs cannot be self governed when it comes to how much they eat. Overeating results in gorging sickness, canine obesity, and sometimes death. An automatic smart dog feeder ensures that the dog only gets the amount of nutrition they need throughout the day. ## Design Concept For a 445 project, it is important to note that the market for indoor automatic dog feeders is saturated with hundreds of brands and models; However, the choices for smart dog feeder for larger outdoor/indoor-outdoor dogs are limited. The project proposed is to fabricate a heavier and robust feeder that will dispense food into a sheltered reciprocal based on users input for parameters such as quantity and frequency. The mechanism of dispensing begins at the reservoir (1) this is above an auger chamber aided by gravity this auger will be driven by a motor into a reciprocal (2). The reciprocal also contains a scale to allow the unit to know how long to run the auger motor based on the user's settings. Once the food is dispensed into the reciprocal the lid is able to open when the RFID tag is in proximity. ## Specifications of design - Scheduled feeding times and amount. (3) - Active weighing to monitor pet's eating habits; While also not allowing continued dispensing resulting in overfill. - RFID proximity access to only permit the pet to eat from reciprocal. - Solar powered with internal battery bank - User notifying system for low feed reservoir or low/loss of power (3) - Tracking feeding paterns to alert owner of illness or loss of appetite (3) ## THE STM32 Cortex M0+ MICROCONTROLLER I/O: ## INPUTS - 2.4 GHz transceiver (4) - Digital scale signal (9) - Voltmeter for charge state of battery (8) - RFID digital signal (7) ## OUTPUTS - 2.4 GHz transceiver (4) - auger motor (5) - reciprocal lid motor (6) ## Footnotes - (1) Sheetmetal container formed into a box/silo that holds 50-60 lbs of dog food - (2) The reciprocal is sheltered and protected by a hinged and motor driven lid. - (3) An app for android or a raspberry pi application for user to unit communication - (4) MKW41Z for Bluetooth low energy app communication - (5) Servo motor dynamic loads - (6) Stepper motor for holding torque - (7) Grove - 125KHz RFID Reader - (8) two resistors - (9) Ardest A/D Converter Weighing Sensor HX711 Balance Module for Load Cell MCU AVR Arduino |
