The pyroelectric sensor or Passive Infrared Sensor (PIR) is activated when you change the IR radiation that reaches it. It is powered by 12 V and connected to the mic input of a XO1. When the sensor is activated, the program emits a 1000 Hz tone and displays a photograph of the moving hot body that triggered the alarm.

In addition to the PIR and laptop, a source of 12V DC is required. For the PIR sensor shown, power requirement is 9 to 16 V DC and current consumption at 12 V is 12 mA, its output is relay NC (normally closed R=0 ohms, open circuit when triggered)
