This paper proposes an innovative Internet of Things (IoT) framework for real-time monitoring of animal health. Imposing sensor technology and wireless communication, the system collects and analyzes vital health parameters, such as temperature, heart rate, and rumination, in livestock or pets by mounting various sensors on the body of the animal. The gathered data is transmitted to a centralized platform (Blynk), from where the owner can access and assess the animal’s well-being. The proposed system offers a proactive approach to animal health care, enabling timely intervention and improving overall health management in agricultural and domestic settings.
