This project is an Home Alarm System made with Arduino Nano 33 IOT. The sensor used for the project is a simple PIR sensor that is activated if the correct password is typed on the keypad. If the PIR ...

This project uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer. This code ...

The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens. The contours on this plastic helps in gathering parallel light ...

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...

The complete circuit diagram for Arduino Based Decorative Christmas Tree is given above. It is pretty simple as we only need to connect a PIR sensor, JQ6500 voice module, and Neo-Pixel LED Strip. The ...

Abstract: In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present ...

Abstract: In this paper, the Arduino based Intruder Detection System employing Rochelle Salt and Pyro-electric or Passive infrared (PIR) Sensor has been proposed. The proposed system employs Rochelle ...
