The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion of a human body by the change in surrounding ambient temperature when a human ...

Simple Arduino motion sensor using PIR sensor and buzzer. How PIRs Work by lady ada PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs ...

Components used in this project: 1x Arduino 101 3x Jumper wire 1x PIR sensor 1x LED light 1x USB cable Background: Arduino 101 is a microcontroller which can take in inputs and produce an output. In ...

Even though Attiny85 is fitting here, I opted for Digispark just because of its plethora of features like USB programming interface, on-board voltage regulator, and Arduino IDE compatibility. The code ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor. When the PIR sensor no longer detects someone in range, ...
