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 ...

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 ...

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 ...

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 ...

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 ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the ...

Working from home with regular video meetings has its challenges, especially if you add kids to the mix. To help avoid embarrassing situations, [Charitha Jayaweera] created Present!, a USB device to ...
