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 ...

There are loads of unique sensors available on the market for Arduino boards ... from intruder detection to home automation. PIR motion sensors use infrared light to detect movement.

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.

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 ...
