The pyroelectric sensor 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.
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.
The PIR sensor needs a supply of 9V minimum, its output is relay NC (normally closed R=0 ohms)
The PIR sensor needs a supply of 9V minimum, its output is relay NC (normally closed R=0 ohms, open circuit when triggered)
