Alarm

Small Sized Loop Alarm

small sized loop alarm

The circuit was constructed to provide an alarm circuit that is reliable, simple, small size, and low in power consumption.

Alarm System Using Radio Waves

Alarm System Using Radio Waves

The circuit was designed to provide an alarm system that would transmit signals across the medium wave or the radio wave.

Burglar Alarm with Expandable Modules

Burglar Alarm with Expandable Modules

The circuit has been designed to provide an alarm system against any form of burglary wherein it can be expanded by adding modules and zones as necessary.

Five Zone Alarm with LED Display

Five Zone Alarm with LED Display

The circuit was constructed to be appropriate with small office or home environment which consists of seven-segment LED to display which zone triggered the alarm while utilizing five independent zones

Six Zone Alarm With LED Display

Six Zone Alarm With LED Display

The circuit was constructed with seven-segment LED to display which zone triggered the alarm while utilizing six independent zones. Buffered CMOS, denoted by suffix B, were used because the gain is very high, they are sensitive to parameter changes in the oscillator circuit and are less stable than unbuffered ICs.

Remote Audio Detection And Security Monitoring

Remote Audio Detection And Security Monitoring

The circuit is designed to detect audio signals on a remote area for security purposes.
