Maintaining regular feeding regimens for pets can be a challenging task for many pet owners, especially in today’s fast-paced and demanding lifestyle. To address this issue, this project introduces a smart pet feeder powered by the ESP8266 NodeMCU, a Wi-Fi-enabled microcontroller that facilitates Internet of Things (IoT) applications. The system allows pet owners to remotely manage and automate feeding schedules, ensuring timely and accurate meal delivery even in their absence. Key features include scheduled feeding, remote activation through a smartphone application, and precise portion control using a servo motor-driven dispensing mechanism. To enhance functionality, sensors such as load cells are used to measure the weight of dispensed food, while infrared (IR) sensors monitor food levels in the storage bin to avoid empty feedings. The entire system is integrated with a cloud-based platform like Blynk or Firebase, which enables real-time data visualization, notifications, and remote control. This smart pet feeder not only enhances pet welfare by maintaining consistent feeding routines but also showcases the potential of embedded systems and real-time automation. The design is scalable and can be upgraded in the future with additional features such as voice command support, camera-based pet monitoring, and AI-driven feeding schedule predictions for smarter pet care management.
