Intruder Alarm System using PIR Sensor This project demonstrates how to build an Intruder Alarm System using an HC-SR501 PIR sensor, Arduino Uno, a 5V relay, and a buzzer. The system detects motion ...

It uses a motion-detecting sensor (PIR sensor) to open or close the door which detects the infrared energy omitted from human's body. When someone comes in front of the door, the infrared energy ...

As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

Arduino Code for Speed Sensor In general, the following code makes Arduino to measure the speed of the moving object using two IR sensors and display the object speed in the I2C 16x2 LCD display. When ...

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 salt based ...

While homemade masks are usually made from fabric [DesignMaker]’s version is much more to a hacker’s taste and includes 3D-printed parts, an Arduino Nano, PIR sensors, an SG90 servo, and some ...
