![]() ![]() Now, as we know the main connections and also the complete circuit of our project, let us move ahead and start making the hardware of our project. The Vero Board is preferred for assembling the circuit on hardware because if we assemble the components on breadboard they may detach from it and the circuit will become short hence, Veroboard is preferred. Let’s make a list of components, purchase them and get started with the project. The best approach to start any project is to make a list of components and going through a brief study of these components because no one will want to stick in the middle of a project just because of a missing component. How to design a PIR Sensor based Intruder Alarm? This Veroboard will be installed at that place of the house where there is more danger of an intruder to get inside of the home. ![]() This circuit is very simple and will be designed on a Veroboard. When the PIR sensor will detect an intruder, it will send a signal to Arduino and the Arduino will sound an alarm. This article is about making an intruder alarm using Arduino and PIR sensor. We can make an intruder alarm circuit at home which will be almost equally efficient for a specific range of distance and will be very low in cost. A burglar alarm or an intruder alarm is basically an electronic device that sounds an alarm when it detects an intruder in the home. These systems are very efficient but costly. So, many security alarm systems are available in the market. Everybody needs to feel secure when they are at home either while sleeping at night or during day time. Street crime is very common in the modern century. ![]()
