PawSync: Smart Automatic Pet Feeder

A project design is presented that enables pet owners to feed their pets without direct interference, improving upon older pet feeder versions. The core motive is to offer a simpler and more efficient method for pet owners to manage their pets' feeding schedules. This system is implemented using the Internet of Things (IoT) and Digital Image Processing. The process begins with a recorded voice message from a speaker to signal the pet's feeding time. An ultrasonic sensor detects the pet's presence, which activates a camera to capture and process an image of the pet. If the system recognizes the animal as the correct pet, a DC motor is activated to dispense food. The implementation is designed for two different pets, utilizing two DC motors to dispense different food types from four containers into two bowls. Upon successful feeding, a notification is sent to the owner's mobile phone via an API. The system also incorporates digital wallet functionalities, enabling users to perform seamless and instant microtransactions while ensuring both confidentiality and integrity of the transaction records. All transaction data is securely logged, ensuring traceability and accountability without compromising user privacy.
