Attention pet owners! Do you ever walk past your pet’s bowl and wonder how long it has been empty? On this #FlashBackFriday we go back to 2011 when Chris Monaco made a tweeting pet bowl using Digi XBee to solve this problem.
Using a force-sensitive resistor and two Digi XBee cellular modules, the pet bowl senses when the water level or amount of food in the bowl is low. It will then send a tweet to alert the owner that the bowl needs to be refilled – a complete wireless solution.
