Product description

This thesis project has developed a system to restrict access based on the simulator touch-memory DS1990A and electronic lock. This device is a microprocessor-based system that produces readable comparison with the simulator code with codes stored in the memory. The system can be reprogrammed at any time by the user. To protect against unauthorized reprogramming the lock master key is used, the code is brought in a read only memory (ROM) of the microcontroller and can not be erased or changed by normal procedure of programming lock.
