摘要：Security mechanism must be reliable so as not easy broken by the offender.Design of the key barriers to work based on the electric current can helpsecurity. Electronic Key Module has components built with two LM311 IC thatform two reference voltage comparator that checks whether a key is thecomparison voltage divider into two reference voltages are eligible for a key canopen. Electronic Key is a model of a safety system that works based on thevoltage produced on the key barriers. A key-shaped tool is used in a stereo jack,in addition to the unique character of these keys is also very difficult for theDuplicate.
