Internet of Things-based Cat Detector System for Monitoring Stray Cats

The population of stray cats in the streets has been on the rise lately. Meanwhile, due to the nature of feral animals that are afraid of humans, combined with human cruelty towards them, the likelihood for these animals to scratch and bite is high. Taming a stray cat is not an easy job and sometimes leads to hostility. Stray cats that are not cared for can contract diseases, some of which can even infect humans, such as febrile fever, pustules, and, in extreme cases, complications that can lead to death. The purpose of this study is to build a monitoring system for the presence of stray cats using IoT (Internet of Things) technology so that animal activists can find out the condition of stray cats and determine the required actions. This system attracts the cat's attention when looking for food so it does not disturb humans. The system’s main controller is a Raspberry Pi microcontroller with three input components, namely a camera and two weight sensors. Pi camera as a camera captures images, while the two weight sensors or load cells determine the amount of feed and water available. With this tool, it is expected that activists can monitor the condition of the cat in real-time through images sent to the application and reports on the weight of the feed.
