I started out again with Arduino (beginner), but I wanted to know if I could connect another human infrared sensor like this to the Arduino Uno. I know how to connect a simple pir like this one, but I dont know for sure how to connect the 12V one (if its possible). Guess the red wire goes to a seperate 12V power supply, brown goes to ground and blue then goes to a digital pin on the arduino arduino? I didnt really understand the description that was available for the 12V sensor, so thats why I am asking (I want to be entirely sure before buying).
Thanks
