With this information, a smart pet feeder utilising the concept of the Internet of Things is designed with functionalities that address those top problems. The smart pet feeder is designed to ease pet owners to automatically feed their pets, interact with their pets in a real-time manner, and monitor their pets’ living environment with the help of the internet and various sensors without them needing to be around the feeder. Arduino Uno board is utilised as the brain of the system, with numerous sensors and modules to serve different functionalities, including weight sensor, temperature sensor, PIR sensor camera module, speaker module, servo motor, LED, and piezo buzzer. A mobile app is designed as well, with the role of being the media for pet owners to control the smart pet feeder remotely using the internet connection.
