Ultrasonic Pet Water Dish Monitor



Using an Parallax ultrasonic sensor, an Arduino and a computer this Ultrasonic Cat Water Dish Monitor project will allow you to monitor the cat dish level from anywhere. I think a cool upgrade would be monitoring and record the time and frequency of usage and temperature. It would be cool to see an increase of water drinks as the temperature in the house got warmer. Have a look at this page for the current water level.
