Review on π DAOKI 5Pcs IR Human Sensor AM312 Mini Detector Module HC-SR312: Automatic PIR Motion Detector for Arduino 2 A1U2, DC 2.7-12V by Larry Morris
All you need is the current specification from the manufacturer.
This compact peer module is ideal for a physical intrusion detection, alarm and interaction system I am building for a server room. I'm currently using it on 5V. It would be nice to have a datasheet so I can determine the effect of changing the voltage and current applied to the module. I've posted a picture of the Arduino sketch I use to determine how long the output pin stays high after motion is detected. If you see a picture you can use the code. Change the PIN to the one you use.
