Survey on Automatic Food Dispenser for Pets Using Sensors

In this fast-paced world, pet owners are finding it difficult to give the needed care for their pets. As a solution, this system develops an Internet of Things (IoT) based automatic pet feeding system using NODE-MCU - ESP-8266 and necessary servo motors for small pets like dogs and cats, addressing feeding schedules during owners’ absence. The smart feeder dispenses precise portions, remotely controlled through the BLYNK IoT app which gives the user complete control of the system and includes sensors that monitor the amount of food remaining and notify the user when it is time to refill the feeder. Sometimes there will be some food which is leftover by the pet which has a great chance of getting contaminated due to the exposure of air in the open. This, when mixed with the upcoming scheduled meal, will affect the pet’s health and cause illness too. To prevent this, the system provides timely removal of the leftover food that is present in the dispensing plate at regular intervals. It promotes healthier eating habits by establishing consistent meal schedules along with timely removal of leftovers and enabling real-time monitoring of consumption patterns, thus enhancing responsible pet ownership and overall pet well-being. It prevents overfeeding, encourages consistent meal routines, and real-time monitoring enhances responsible pet care.
