Pet doors were initially created for the consumer that has a pet but does not want to hassle with letting the pet in and out of the house or allowing them access to food and shelter. The market has been flooded with automatic pet doors that are activated by a magnetic field, radio frequency or other activation signal. These doors are designed to be installed in a door or door frame. These doors, however, are very expensive, made of low-cost materials, and are limited in the places that they can be installed. Also, because they commonly use elaborate motors built with inexpensive parts, the motors often break and are unable to be replaced, forcing the consumer to purchase an entirely new apparatus. There is plenty of room for improvement. It is believed that simpler parts can be used more successfully and at a much lower cost to the consumer. As well, these doors should be able to be placed wherever the consumer would like: a barn wall, dog kennel, food box, shelter, etc. For this experiment it is hypothesized that a consistent source of activation will be used and that a working model within the above parameters will be built and operable. The goal is to create a product that can be easily understood by the consumer and would allow for the replacement and fixing of parts.
