IoT - Based Cat Feeding and Cage Door Control

Abstract

A much-loved pet is a cat because of its cute and adorable behavior, in keeping animals sometimes many owners have busy outside the home, so that the basic needs of cats such as cage conditions, feed, and activities outside the cage to play are less controlled. In this increasingly sophisticated era, there are many technologies that can be utilized, especially the utilization of the Internet of Things. Therefore a tool is needed that can control the cat's cage door and feed when the owner is busy, this tool uses ESP32 as a microcontroller and telegram application as a remote control. Where this tool uses the HCSR04 Ultrasonic Sensor as a distance detector for cats outside the cage which is limited to 100 cm from the sensor and the HCSR501 PIR Sensor as a detection of cat movement in the cage. When the distance of the cat is less than 20 cm from the ultrasonic sensor then the door will open and the PIR sensor will detect the cat, if the cat is detected then the door will close, from the test results using ultrasonic sensors and rulers it is found that measurements at a distance of less than 50 cm have a smaller difference than the distance of more than 50 cm.
