In the microcontroller era today, Arduino ... at its sensor input port. As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion ...

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...

Sometimes, projects start in somewhat unlikely places ... Get close enough to this raven and you’ll set off the PIR sensor, which triggers lighting and sound effects, including some spooky ...

When something passes in front of a PIR sensor it detects the change in background temperature and then triggers an output voltage. This voltage can be read by an Arduino digital input and then ...

Over the years the ideas have become much more polished, as we can see with this Gesture Recognition with PIR sensors project ... from 8 adjacent points. An Arduino reads these temperature ...

It’s a fairly simple project, too ... as “3”—these correspond to where you plugged the PIR sensor and power relay into the Arduino. With your fan unplugged, turn it on and set it to ...

The Arduino microcontroller is at the heart of the project, where all the sensors are connected. The Raspberry Pi is responsible for analyzing the data, sending notifications to the user based on ...
