Abstract

The Smart IoT-Based Automated Pet Feeder is designed to solve the problem of inconsistent pet feeding routines. By combining IoT, sensors, and microcontrollers, the system ensures pets receive food on time whether the owner is home or not. The feeder uses a servo-controlled dispenser and an IR object detection sensor to release food when a pet is detected or based on a preset timer. Data is sent to ThingSpeak cloud, where owners can monitor feeding history. A custom mobile application allows remote scheduling, emergency feeding, and portion control. The OLED display provides on-device updates, while a buzzer and LEDs indicate system status and alerts. This innovation ensures healthy feeding practices, reduces owner stress, and prevents pet overfeeding or underfeeding. With its user-friendly design and real-time monitoring capabilities, the system is ideal for pet owners seeking convenience and reliability in daily pet care.

Project Information

This automated pet feeder is powered by an ESP32 microcontroller due to its built-in Wi-Fi for seamless IoT integration. A servo motor drives the dispensing mechanism, ensuring precise food portions. The OLED display shows live feeding status, schedule, and system health. IR sensors ensure food is dispensed only when a pet is present in detection mode. The system supports manual override via mobile app, giving flexibility to owners. ThingSpeak cloud integration logs feeding times, enabling owners to review patterns and make adjustments. LED indicators provide visual feedback (power, feeding, and error status), while a buzzer alerts for malfunctions or successful feeding. The mobile app allows real-time notifications, scheduling, and manual control. This combination of IoT, automation, and feedback systems makes the feeder highly reliable, ensuring pets are fed properly even in the absence of their owners.

Project Objective

The objective of this project is to design a smart automated pet feeder that ensures timely and controlled feeding for pets such as dogs, cats, and fish. The system uses an ESP32 microcontroller with an OLED display to show real-time feeding schedules. A servo motor controls the food dispenser, while IR sensors detect the presence of a pet before dispensing. The feeder operates in two modes: timer-based and pet-detection-based. Integration with ThingSpeak cloud provides data logging and monitoring, while a custom mobile app allows owners to set feeding times, portion sizes, and receive alerts. Additional features include a buzzer for alerts, LED indicators for system status, and emergency manual feeding via the app. This project aims to provide a reliable, cost-effective, and user-friendly solution for pet owners who cannot always be present at home.

Conclusion

The Smart IoT-Based Automated Pet Feeder is a practical and innovative solution that combines automation, IoT, and sensor technology to address the daily challenge of pet feeding. Its dual-mode functionality ensures flexibility, allowing pets to be fed based on a timer or presence detection. With its integration into ThingSpeak cloud and a custom mobile app, owners can remotely manage feeding schedules, track history, and receive real-time notifications. Safety features like buzzer alerts, LED indicators, and OLED display enhance reliability. Although challenges like internet dependency and limited storage exist, the system remains a cost-effective alternative to commercial feeders. Future improvements such as AI portion control, camera integration, and voice assistant support will make it even more advanced. Ultimately, this project ensures pets are well-cared for while giving owners peace of mind, especially during their absence.
