RFID Cat Feeder
Author: Gherman Maria Irina
Project Description
RFID Cat Feeder is a “smart” feeder that opens up only when a certain cat wants to eat. It can do this by reading an RFID tag on its collar, or ideally its microchip. The purpose of such a feeder is to stop a gluttonous cat from eating all the food.
Hardware Description
Parts list:
- ESP32
- RC522 RFID reader + RFID tag
- HC-SR04 ultrasonic sensor
- 2 x LED (1 green, 1 red)
- Button
- TowerPro SG90 servo motor
The hardware is relatively simple. ESP32 gets info about the RFID tag from an RFID reader. The door motion is controlled by a servo motor. Registering a new tag is done through a button. Two LEDs help the user know what the feeder is currently doing.
To have a safety mechanism so that the door doesn't close on the cat, the feeder uses an ultrasonic sensor to sense if there is a cat in front of it.
