Auto Alarm
SI is an external key switch. The alarm allows a delay of 0 to 45 seconds after SI is operated before the circuit is armed. During this period, LED1 lights up green. After this delay, LED1 lights red, indicating that...
radio wave alarm
This simple alarm circuit can effectively alert users to the presence of an intruder, providing notification before they even reach the doorstep.
The circuit is designed to be straightforward and efficient, utilizing basic electronic components to create an effective security solution....
Personal Alarm
This circuit, enclosed in a small plastic box, can be placed into a bag or handbag. A small magnet is placed close to the reed switch and connected to the hand or the clothes of the person carrying the bag...
Enhanced Alarm
This is an enhanced version of the simple Garage/Shed Alarm. The entry and exit delays have been increased to approximately 30 seconds, and a timed siren cut-off and automatic reset have been added. The LED has been replaced with an...
House Alarm Loop Circuit
This circuit features open and closed loop contacts (switches 1, 2, 3) that activate the alarm, which remains on for a duration of 5 to 10 minutes. The triggering delay for entrance and exit is set to 27 seconds. Additionally,...
Alarm interface circuit
Alarm interface circuitry featuring a two-color light-emitting diode (LED) display. When LAi is at a high level and LBi is low, the green LED lights up; conversely, if LAi is low and LBi is high, the red LED lights up....
Alarm
This is a simple and easy-to-build multi-tone alarm circuit that can be utilized in burglar alarms or sirens. The circuit is based on the dual op-amp MC1458 and LM380. The two op-amps within the MC1458 are configured to generate square...
Alarm Sounder For Flex Switch Circuit
This is a cross-sectional diagram of a flex switch. They can be used as pushbuttons or even position sensors. This schematic diagram shows an oscillator, which is used as an alarm sounder, triggered by a flex switch.
The flex switch is...
Gas Leakage Sensor Alarm Circuit Engineering Project using 555 Timer and MQ6 SEN 1327 Gas Sensor Module
This article discusses a home security alarm circuit designed to detect LPG gas leakage. The circuit utilizes a gas sensor module, SEN 1327, which incorporates a QM 6 gas sensor. The output signal from this gas sensor module is used...
