One advantage of using Arduino as a security system is the flexibility ... The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion of ...

Get close enough to this raven and you’ll set off the PIR sensor, which triggers lighting ... This bird’s brain is an Arduino Nano, which is protected from the 12V supply with a boost converter.

Following is the Arduino Sketch, tailored for Digispark Attiny85 Development board! /* * Grove-mini PIR Motion Sensor Module (v1.0) * Quick Test Sketch / Digispark Attiny85 Dev. Board * Author: ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use (the kind with a white golf ball-like semi-sphere lens, electrical connectors called ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these ...

You’ll see PIRPin defined as “2” and OutPin defined as “3”—these correspond to where you plugged the PIR sensor and power relay into the Arduino. With your fan unplugged, turn it on ...

When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR sensors are used for applications such as automatically turning on lights when someone ...
