Wireless Remote Control Lock

Abstract:

Almost everyone has been in the situation where they are locked out of their house and it would be helpful if there is a way for them to lock or unlock the door without using a key. This paper explains the design of a deadbolt lock that is controlled through the phone line and can be locked or unlocked remotely from anywhere. This project consists of circuit to pick up a phone call and determine the keys pressed by the user at the other end of the telephone line as well as the software to verify an input password and ultimately control the lock. The paper details the steps it took to create the final design of the project, the problems encountered, and the final results. It also examines the estimated cost of manufacturing this product.
