| Abstract: | The project work is the Design and Cons'.rllction of Dark Activated Intruder Alarm System. It is design to provide security against intruder, using sensor and time-out delay circuitry. The sensor is sensitive to shadow that is cast on it which through comparator activates the time out delay section. This section in turn holds the signal for 5 seconds before it is sent to the alarm section. The reason for this delay is to avoid false alarm due to presser that may cross the sensor. The alarm is made of a piezoelectric alaml which . powered by 9v supply. The whole system is powered by on de supply of 9v |
