Design and Simulation of Drawer Alarm

The traditional way of drawer protection is to install a physical lock. The disadvantage of this method is that the lock will wear out after a period of use. And once the key is lost, the drawer cannot be opened, and the lock must be forcibly picked. Such operation will damage the drawer. Based on the above, this paper designed a new type of drawer anti-theft alarm, including the structural design and the design of the circuit. And the system successfully carried out simulation on pro-E and Multisim. The results show that the design is feasible.
