Laser Security Alarm Circuit Diagram using IC 555 and LM358 We have built some security alarms like PIR sensor based motion detector and burglar alarm circuit. In this circuit we are going to build a laser security alarm which uses a laser light and a laser light detector circuit. It gets activated when someone crosses it. LASER BURGLAR ALARM CIRCUIT | MyCircuits9 SIMPLE LASER BURGLAR ALARM CIRCUIT It is an advanced, simple, efficient and low cost circuit. You can use this circuit on Home, office, locker or anywhere for Security purpose. As the name suggests, the circuit is based on Laser. We all know about the features of Laser, Long Range, pointed beam, Low power consumption and so on. LASER BASED INTRUDER ALARM | Electronics For You You can use this laser based intruder alarm conveniently at the entrance of a hall or any other similar location to protect the same from unauthorised access as and when desired. Its range can be extended further to protect the perimeter of a building from unauthorised intrusion by using a cascade arrangement of multiple alarms. The […] Laser Based Intruder Alarm | Circuits Projects You can use this laser based intruder alarm conveniently at the entrance of a hall or any other similar location to protect the same from unauthorised access as and when desired. Its range can be extended further to protect the perimeter of a building from unauthorised intrusion by using a cascade arrangement of multiple alarms. Laser Security Alarm Circuit theorycircuit Laser security alarm circuit produce highly audible buzzer beep sound when the laser light blocked. Here LDR placed to sense the laser light from the laser diode. Circuit diagram Construction & Working Two NPN (BC548) transistors implemented in this security alarm circuit as a switching device. Laser Security System Locks Working Along With Circuit Diagram Laser Security System Locks Working Along With Circuit Diagram. Laser door alarm is based on the interruption of Laser beam. The laser pointer is used as the source of light beam. If somebody tries to break the laser path, then an alarm will be generated in a few seconds. Normally laser door alarm circuit will have two sections. Intruder Alarm – Electronics Project The circuit of intruder alarm can be used against thieves or intruders. Circuit description of intruder alarm. The project intruder alarm consist two circuits each of transmitter and receiver separately. Transmitter section comprising a laser diode and power is given from a 9V power supply. Long Range Wireless Burglar Alarm Security System This long range photoelectric burglar alarm system works during the day time also to protect and alert you about the burglars in your commercial buildings, banks, big compounds, etc. This burglar alarm circuit comprises both laser transmitter and receiver sections, which are to be placed on the opposite pillars of the entry gate.

Last Updated on April 15, 2019 by Swagatam 64 ments. ... Burglar Alarm Using a Laser Beam. Build a Simple Laser Tripwire Alarm | Make: If your alarm circuit is powered by 4.5 volts (three AA batteries), then it is possible to power the laser pointer from this battery pack as well. All you have to do is connect the terminals of the laser pointer to the batteries of the alarm circuit. One terminal of the laser pointer is a spring that sticks out of the internal circuit board. Simple Laser Alarm Circuit Making Easy Circuits Home » Simple Laser Alarm Circuit. ... The suggested laser beam burglar alarm circuit for safeguarding harvests from beasts and invaders may be seen in the picture below. The concept presents itself remarkably simple, and utilizes an IC 555 dependent monostable multivibrator stage together with an LDR sensor.
